Requirements
The Avaya Definity G3 integration supports configurations of the following components:
Phone System
•Avaya Definity G3-series phone system. The voice messaging ports that connect to the PIMG units must be compatible with the 7434ND, 8434, 8434D, or 8434DX digital phones.
Caution You must use 2-wire line cards for these voice messaging ports. Otherwise, the voice messaging ports will not be compatible with the 7434ND, 8434, 8434D, or 8434DX digital phones.
•Software version 4 or later.
•One or more of the applicable PIMG units. For details, refer to the "Supported Circuit-Switched Phone System Integrations" section in the applicable Supported Hardware and Software, and Support Policies at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.
•The voice messaging ports in the phone system connected by digital lines to the ports on the PIMG units.
We recommend that you connect the voice messaging ports on the phone system to the ports on the PIMG units in a planned manner to simplify troubleshooting. For example, the first phone system voice messaging port connects to the first port on the first PIMG unit, the second phone system voice messaging port connects to the second port on the first PIMG unit, and so on.
•The PIMG units connected to the same LAN or WAN that Cisco Unity is connected to.
•If the PIMG units connect to a WAN, the requirements for the WAN network connections are:
–For G.729a codec formatting, a minimum of 32.76 Kbps guaranteed bandwidth for each voice messaging port.
Caution If you use G.729a codec formatting over a WAN, you must disable comfort noise. Otherwise, callers will hear loud comfort noise at certain points. For details, see the "Appendix: PIMG Integrations Over a WAN That Use the G.729a Codec Must Disable Comfort Noise" section.
–For G.711 codec formatting, a minimum of 91.56 Kbps guaranteed bandwidth for each voice messaging port.
–No network devices that implement network address translation (NAT).
–A maximum 200 ms network latency.
•The phone system ready for the integration, as described in the documentation for the phone system.
Cisco Unity Server
•Cisco Unity installed and ready for the integration, as described in the applicable Cisco Unity installation guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.
•A license that enables the applicable number of voice messaging ports.
Integration Description
The Avaya Definity G3 PIMG integration sends call information and voice connections through the digital lines, which connect the phone system to the PIMG units. The PIMG units communicate with the Cisco Unity server through the LAN or WAN by using Session Initiation Protocol (SIP). Figure 1 shows the required connections.
Figure 1 Connections Between the Phone System and Cisco Unity
Call Information
The phone system sends the following information with forwarded calls:
•The extension of the called party
•The extension of the calling party (for internal calls) or the phone number of the calling party (if it is an external call and the system uses caller ID)
•The reason for the forward (the extension is busy, does not answer, or is set to forward all calls)
Cisco Unity uses this information to answer the call appropriately. For example, a call forwarded to Cisco Unity is answered with the personal greeting of the subscriber. If the phone system routes the call to Cisco Unity without this information, Cisco Unity answers with the opening greeting.
Integration Functionality
The Avaya Definity G3 integration with Cisco Unity provides the following integration features:
•Call forward to personal greeting
•Call forward to busy greeting
•Caller ID
•Easy message access (a subscriber can retrieve messages without entering an ID because Cisco Unity identifies the subscriber based on the extension from which the call originated; a password may be required)
•Identified subscriber messaging (Cisco Unity identifies the subscriber who leaves a message during a forwarded internal call, based on the extension from which the call originated)
•Message waiting indication (MWI)
Integrations with Multiple Phone Systems
Depending on the version, Cisco Unity can be integrated with two or more phone systems:
•Cisco Unity 4.0 and 4.1 can be integrated with a maximum of two phone systems at one time. For information on and instructions for integrating Cisco Unity with two phone systems, refer to the Dual Phone System Integration Guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_configuration_guide09186a0080211b2e.html.
•Cisco Unity 4.2 and later can be integrated with two or more phone systems at one time. For information on the maximum supported combinations and instructions for integrating Cisco Unity with multiple phone systems, refer to the Multiple Phone System Integration Guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_configuration_guide09186a00806192a3.html.
Planning How the Voice Messaging Ports Will Be Used by Cisco Unity
Before programming the phone system, you need to plan how the voice messaging ports will be used by Cisco Unity. The following considerations will affect the programming for the phone system (for example, setting up the hunt group or call forwarding for the voice messaging ports):
•The number of voice messaging ports installed.
•The number of voice messaging ports that will answer calls.
•The number of voice messaging ports that will only dial out, for example, to send message notification, to set message waiting indicators (MWIs), to make AMIS deliveries, and to make telephone record and playback (TRAP) connections.
The following table describes the voice messaging port settings in Cisco Unity that can be set in UTIM, and that are displayed as read-only text on the System > Ports page of the Cisco Unity Administrator.
The Number of Voice Messaging Ports to Install
The number of voice messaging ports to install depends on numerous factors, including:
•The number of calls Cisco Unity will answer when call traffic is at its peak.
•The expected length of each message that callers will record and that subscribers will listen to.
•The number of subscribers.
•The number of ports that will be set to dial out only.
•The number of calls made for message notification.
•The number of MWIs that will be activated when call traffic is at its peak.
•The number of AMIS delivery calls.
•The number of TRAP connections needed when call traffic is at its peak. (TRAP connections are used by Cisco Unity web applications to play back and record over the phone.)
•The number of calls that will use the automated attendant and call handlers when call traffic is at its peak.
It is best to install only the number of voice messaging ports that are needed so that system resources are not allocated to unused ports.
The Number of Voice Messaging Ports That Will Answer Calls
The calls that the voice messaging ports answer can be incoming calls from unidentified callers or from subscribers. Typically, the voice messaging ports that answer calls are the busiest.
You can set voice messaging ports to both answer calls and to dial out (for example, to send message notifications). However, when the voice messaging ports perform more than one function and are very active (for example, answering many calls), the other functions may be delayed until the voice messaging port is free (for example, message notifications cannot be sent until there are fewer calls to answer). For best performance, dedicate certain voice messaging ports for only answering incoming calls, and dedicate other ports for only dialing out. Separating these port functions eliminates the possibility of a collision, in which an incoming call arrives on a port at the same time that Cisco Unity takes the port off-hook to dial out.
The Number of Voice Messaging Ports That Will Only Dial Out, and Not Answer Calls
Ports that will only dial out and will not answer calls can do one or more of the following:
•Notify subscribers by phone, pager, or e-mail of messages that have arrived.
•Turn MWIs on and off for subscriber extensions.
•Make outbound AMIS calls to deliver voice messages from Cisco Unity subscribers to users on another voice messaging system. (This action is available only with the AMIS licensed feature.)
•Make a TRAP connection so that subscribers can use the phone as a recording and playback device in Cisco Unity web applications.
Typically, these voice messaging ports are the least busy ports.
Caution In programming the phone system, do not send calls to voice messaging ports in Cisco Unity that cannot answer calls (voice messaging ports that are not set to Answer Calls). For example, if a voice messaging port is set only to Dialout MWI, do not send calls to it.
Preparing for Programming the Phone System
Record your decisions about the voice messaging ports to guide you in programming the phone system.
Programming the Avaya Definity G3 Phone System
If you use programming options other than those supplied in the following procedure, the performance of the integration may be affected.
Caution In programming the phone system, do not send calls to voice messaging ports in Cisco Unity that cannot answer calls (voice messaging ports that are not set to Answer Calls). For example, if a voice messaging port is set only to Dialout MWI, do not send calls to it.
Do the following procedure.
To Program the Avaya Definity G3 Phone System
Step 1 Create a coverage path which contains the PIMG unit hunt group number as the coverage point.
Step 2 Assign the coverage path that you created in Step 1 to the user stations that must forward to the voice messaging ports on the PIMG units when calls are not answered or when the user station is busy, based on one of the Cisco Unity call transfer types shown in Table 2.
Step 3 Use the Add Station <extension number> command (for example, Add Station 2999) to assign an extension number for each voice messaging port, which is a digital line that connects to the PIMG unit. Set the voice messaging port options (Table 3) and button assignments (Table 4), and press Enter.
Note We recommend that you distribute the voice messaging ports among multiple phone system line cards so that call processing can continue even if a line card becomes inactive.
Table 4 Button Assignments for All Lines
Button Assignment Setting1

lwc-cancel
Step 4 Use the Add Hunt <hunt group number> command (for example, Add Hunt 1) to assign a the voice messaging ports to a hunt group. Set the following options.
Step 5 Enter the group member assignments for the voice messaging ports that will answer calls and press Enter.
If you plan to set the voice messaging ports to either answer calls or to dial out (for example, to set MWIs), make sure that you include in the hunt group only the voice messaging ports that will be set to answer calls.
For smaller systems, include in the hunt group all voice messaging ports when the ports will be set to both answer calls and dial out (for example, to set MWIs).
Note You can use alternate extensions to create multiple line appearances, enable easy message access from cell phones, and simplify addressing messages to subscribers at different locations in Cisco Unity. Enabling alternate MWIs allows Cisco Unity to turn MWIs on at more than one extension. For details, see the "Appendix: Using Alternate Extensions and MWIs" section.

Step 1 From Phone 2, enter the access code necessary to get an outside line, then enter the number outside callers use to dial directly to Cisco Unity.
Step 2 On the Status Monitor, note which port handles this call.
Step 3 When you hear the opening greeting, enter the extension for Phone 1. Hearing the opening greeting means that the port is configured correctly.
Step 4 Confirm that Phone 1 rings and that you hear a ringback tone on Phone 2. Hearing a ringback tone means that Cisco Unity correctly released the call and transferred it to Phone 1.
Step 5 Leaving Phone 1 unanswered, confirm that the state of the port handling the call changes to "Idle." This state means that release transfer is successful.
Step 6 Confirm that, after the number of rings that the phone system is set to wait, the call is forwarded to Cisco Unity and that you hear the greeting for the test subscriber. Hearing the greeting means that the phone system forwarded the unanswered call and the call-forward information to Cisco Unity, which correctly interpreted the information.
Step 7 On the Status Monitor, note which port handles this call.
Step 8 Leave a message for the test subscriber and hang up Phone 2.
Step 9 On the Status Monitor, confirm that the state of the port handling the call changes to "Idle." This state means that the port was successfully released when the call ended.
Step 10 Confirm that the MWI on Phone 1 is activated. The activated MWI means that the phone system and Cisco Unity are successfully integrated for turning on MWIs.
To Test Listening to Messages
Step 1 From Phone 1, enter the internal pilot number for Cisco Unity.
Step 2 When asked for your password, enter the default password. Hearing the request for your password means that the phone system sent the necessary call information to Cisco Unity, which correctly interpreted the information.
Step 3 Confirm that you hear the recorded voice name for the test subscriber (if you did not record a voice name for the test subscriber, you will hear the extension number for Phone 1). Hearing the voice name means that Cisco Unity correctly identified the subscriber by the extension.
Step 4 When asked whether you want to listen to your message, press 1.
Step 5 After listening to the message, press 3 to delete the message.
Step 6 Confirm that the MWI on Phone 1 is deactivated. The deactivated MWI means that the phone system and Cisco Unity are successfully integrated for turning off MWIs.
Step 7 Hang up Phone 1.
Step 8 On the Status Monitor, confirm that the state of the port handling the call changes to "Idle." This state means that the port was successfully released when the call ended.

Step 2 Under Transfer Type, click Supervise Transfer.
Step 3 Set the Rings to Wait For field to 3.
Step 4 Click the Save icon.
To Test Supervised Transfer
Step 1 From Phone 2, enter the access code necessary to get an outside line, then enter the number outside callers use to dial directly to Cisco Unity.
Step 2 On the Status Monitor, note which port handles this call.
Step 3 When you hear the opening greeting, enter the extension for Phone 1. Hearing the opening greeting means that the port is configured correctly.
Step 4 Confirm that Phone 1 rings and that you do not hear a ringback tone on Phone 2. Instead, you should hear the indication your phone system uses to mean that the call is on hold (for example, music or beeps).
Step 5 Leaving Phone 1 unanswered, confirm that the state of the port handling the call remains "Busy." This state and hearing an indication that you are on hold mean that Cisco Unity is supervising the transfer.
Step 6 Confirm that, after three rings, you hear the greeting for the test subscriber. Hearing the greeting means that Cisco Unity successfully recalled the supervised-transfer call.
Step 7 During the greeting, hang up Phone 2.
Step 8 On the Status Monitor, confirm that the state of the port handling the call changes to "Idle." This state means that the port was successfully released when the call ended.
To Delete the Test Subscriber
Step 1 In the Cisco Unity Administrator, go to the Subscribers > Subscribers > Profile page.
If the name of the test subscriber is not displayed, click the Find icon (the magnifying glass) in the title bar, then click Find, and select the name of the test subscriber in the list that appears.

Integrating a Secondary Server for Cisco Unity Failover
For Cisco Unity 4.1 and later, the Cisco Unity failover feature enables a secondary server to provide voice messaging services when the primary server becomes inactive. For information on installing a secondary server for failover, refer to the applicable Cisco Unity installation guide, available at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.
The Cisco Unity failover feature is not available when this phone system is integrated with Cisco Unity 4.0 through PIMG units.
For information on Cisco Unity failover, refer to the Cisco Unity Failover Configuration and Administration Guide. The Domino version of the guide is available at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_feature_guide_book09186a00803f70f3.html. The Exchange version of the guide is available at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_feature_guide_book09186a00801b9241.html.
Requirements
The following components are required to integrate a secondary server:
•One secondary server for each primary server installed and ready for the integration, as described in the applicable Cisco Unity installation guide and earlier in this integration guide.
•A license that enables failover.
Integration Description
The Avaya Definity G3 phone system sends call information and voice connections through the digital lines to the PIMG units. The PIMG units communicate with the primary and secondary servers through the LAN or WAN by using Session Initiation Protocol (SIP). Figure 2 shows the required connections.
Figure 2 Connections Between the Phone System and the Cisco Unity Servers
The primary and secondary servers act in the following manner:
•When the primary server is operating normally, the secondary server is inactive.
•When the primary server becomes inactive, the secondary server becomes active.
•When the primary server becomes active again, the secondary server becomes inactive.
Setting Up the Secondary Server for Failover
Do the following procedure to integrate the secondary server.
To Set Up the Secondary Server for Failover
Step 1 Install a secondary server with the same configuration as the primary server. For installation instructions, refer to the applicable Cisco Unity installation guide.
Step 2 On the Windows Start menu of the secondary server, click Programs > Cisco Unity > Manage Integrations. The UTIM window appears.
Step 3 On the Integration menu of the UTIM window, click New. The Telephony Integration Setup Wizard appears.
Step 4 Enter the settings to match the integration settings on the primary server.
Note We recommend not reassigning any unassigned subscribers and call handlers to the new integration, if you are asked by the wizard. Failover replication will automatically assign the correct integration.
Step 5 At the prompt to restart the Cisco Unity services, click Yes.
Note When restarting the Cisco Unity services, use the UTIM prompt instead of the Cisco Unity icon in the Windows taskbar. The taskbar icon does not restart all of the Cisco Unity services.
Step 6 After Cisco Unity restarts, on the Windows Start menu of the Cisco Unity server, click Programs > Cisco Unity > Manage Integrations. UTIM appears.
Step 7 In the left pane of the UTIM window, click the phone system integration that you created in Step 3.
Step 8 For Cisco Unity 4.0 and 4.1, continue to Step 9.
For Cisco Unity 4.2 and later, do the following substeps.
a. In the right pane, click Properties.
b. On the Integration tab, compare the setting of the Integration ID field for the secondary server to the setting of the Integration ID field for the primary server.
c. If the integration IDs of the phone system on the primary and secondary server are the same, continue to Step 9.
If the integration IDs of the phone system on the primary and secondary servers are different, on the secondary server, click Modify Integration ID.
d. When cautioned that subscribers associated with the current Integration ID setting will not be automatically associated with the new Integration ID setting, click OK.
e. In the Modify Integration ID dialog box, in the Enter New Integration ID field, enter the Integration ID setting for the phone system on the primary server and click OK.
f. Click Save.
g. At the prompt to restart the Cisco Unity services, click Yes.
h. In the left pane, click the phone system integration that you created in Step 3.
Step 9 In the right pane, click the Ports tab.
Step 10 Enter the port settings to match the port settings on the primary server.
Caution In programming the phone system, do not send calls to voice messaging ports in Cisco Unity that cannot answer calls (voice messaging ports that are not set to Answer Calls). For example, if a voice messaging port is set only to Message Notification, do not send calls to it.
Step 11 Click Save.
Step 12 Repeat Step 9 through Step 11 for each remaining PIMG unit in the phone system integration.
Step 13 Exit UTIM.
Changing the Settings for an Existing Integration
After the integration is set up, if you want to change any of its settings (for example, to add or remove voice messaging ports for an integration), do the following procedure.
To Change the Settings for an Integration
Step 1 On the Cisco Unity server, on the Windows Start menu, click Programs > Cisco Unity > Manage Integrations. The UTIM window appears.
Step 2 In the left pane, double-click Unity Server. The existing integrations appear.
Step 3 Click the integration you want to modify.
Step 4 In the right pane, click the name of the cluster, phone system, or PIMG unit (depending on your integration) for the integration.
Step 5 In the right pane, click the applicable tab for the integration.
Step 6 Enter new settings in the fields that you want to change.
Caution If you are adding or removing voice messaging ports, make sure you change the settings for the individual ports so that there are an appropriate number of ports set to answer calls and an appropriate number of ports set to dial out.
Step 7 In the UTIM window, click Save.
Step 8 If prompted, restart the Cisco Unity services.
Caution Do not edit the phone configuration file (also known as the switch ini file) to customize this integration. If you change the settings in this file, the integration may not function correctly.
Deleting an Existing Integration
If you want to delete an existing integration (for example, you have replaced the phone system with which Cisco Unity originally integrated), do the following procedure.
To Delete an Existing Integration
Step 1 On the Cisco Unity server, on the Windows Start menu, click Programs > Cisco Unity > Manage Integrations. The UTIM window appears.
Step 2 In the left pane, double-click Unity Server. The existing integrations appear.
Step 3 Click the integration that you want to delete.
Step 4 On the Integration menu, click Delete.
Step 5 Follow the on-screen instructions to assign the subscribers of the deleted phone system integration to another phone system integration.
Step 6 At the prompt to restart the Cisco Unity services, click Yes. The Cisco Unity services restart.
Alternatively, you can restart the Cisco Unity services in UTIM on the Tools menu by clicking Restart Cisco Unity.
Step 7 If the integration you deleted used voice cards, remove the voice cards from the Cisco Unity server.
Appendix: Adjusting the Recording Gain for PIMG Units
If recordings are too quiet or too loud, do the following procedure to adjust the recording gain for the PIMG units.
To Adjust the Recording Gain for PIMG Units
Step 1 In a web browser, go to http://<IP address of PIMG unit>.
Step 2 On the System Login page, enter the user name and password.
Step 3 Click Log On.
Step 4 Go to http://<IP address of PIMG unit>/dsp.htm.
Step 5 In the TDM to IP Gain field, increase the value to make recordings louder, or lower the value to make recordings quieter.
Caution Increasing the recording gain too much can cause the PIMG unit to fail to recognize DTMF tones, which will result in integration problems. If DTMF recognition problems occur after increasing the recording gain, decrease the value in the TDM to IP Gain field.
Step 6 Click Apply Changes.
Step 7 Repeat Step 1 through Step 6 for all remaining PIMG units.
Appendix: Using Alternate Extensions and MWIs
Alternate Extensions
In addition to the "primary" extension that you specify for subscribers, you can assign subscribers up to nine alternate extensions. (The primary extension is the one that you assign to each subscriber when you create his or her subscriber account; it is listed on the Subscribers > Subscribers > Profile page.)
Reasons to Use Alternate Extensions
There are several reasons that you may want to specify alternate extensions for subscribers. For example, if you have more than one Cisco Unity server that accesses a single, corporate-wide directory, you may want to use alternate extensions to simplify addressing messages to subscribers at the different locations. With alternate extensions, the number that a subscriber uses when addressing a message to someone at another location can be the same number that the subscriber dials when calling. You may also want to use alternate extensions to:
•Handle multiple line appearances on subscriber phones.
•Offer easy message access on direct calls from a cell phone, home phone, or phone at an alternate work site (assuming that the phone number is passed along to Cisco Unity from these other phone systems). In addition, when such phones are used as alternate extensions, and are set to forward to Cisco Unity, callers can listen to the subscriber greeting, and leave messages for the subscriber just as they would when dialing the primary extension for the subscriber.
Tip To reduce the number of requests from subscribers who want alternate extensions set up for multiple cell phones, home phones, and other phones, give subscribers class of service (COS) rights to specify their own set of alternate extensions. (See the Subscribers > Class of Service > Profile page.) With proper COS rights, a subscriber can specify up to five alternate extensions in the Cisco Unity Assistant—in addition to the nine that you can specify on the Subscribers > Alternate Extensions page in the Cisco Unity Administrator.
•Enable URL-based extensions in Cisco Unity for an integration with a SIP phone system.
How Alternate Extensions Work
Before you set up alternate extensions, review the following list for information on how alternate extensions work:
•Alternate extensions cannot exceed 30 characters in length. By default, each administrator-defined alternate extension must be at least 3 characters in length, while subscriber-defined alternate extensions must be at least 10 characters.
You can use the Advanced Settings tool in Tools Depot to specify a minimum extension length for the extensions entered in the Cisco Unity Administrator and the Cisco Unity Assistant. Refer to the Advanced Settings Tool Help for details on using the settings. Respectively, the settings are Administration—Set the Minimum Length for Locations, and Administration—Set the Minimum Length for Subscriber-Defined Alternate Extensions.
•You can control whether subscribers can use the Cisco Unity Assistant to view the alternate extensions that you specify in the Cisco Unity Administrator. To do so, see the Subscribers > Class of Service > Profile page. The Subscriber-Defined Alternate Extension table displays the alternate extensions that the subscriber adds.
•Neither the Cisco Unity Administrator nor the Cisco Unity Assistant will accept an extension that is already assigned to another subscriber (either as a primary or alternate extension), or to a public distribution list, call handler, directory handler, or interview handler. Cisco Unity verifies that each alternate extension is unique—up to the dialing domain level, if applicable—before allowing either an administrator or a subscriber to create it.
•All alternate extensions use the same transfer settings as the primary extension.
•In many cases, Cisco Unity can activate a message waiting indicator (MWI) for an alternate extension. However, depending on the phones and phone systems involved, some additional phone system programming may be required to set this up.
Setting Up Alternate Extensions
Do the applicable procedure to add, modify, or delete alternate extensions:
•To Add Administrator-Defined Alternate Extensions
•To Modify or Delete Alternate Extension(s)
To Add Administrator-Defined Alternate Extensions
Step 1 In the Cisco Unity Administrator, go to any Subscribers > Alternate Extensions page.
Step 2 In the Administrator-Defined Alternate Extensions table, enter an extension in any row. When entering characters in the Alternate Extensions table, consider the following:
•You can enter an extension up to 30 characters in length. (SIP integrations can use up to 30 alphanumeric characters.)
•Each extension must be unique—up to the dialing domain level, if applicable.
•Enter digits 0 through 9. Do not use spaces, dashes, or parentheses.
•For SIP integrations, you can also enter a valid alias for a SIP URL. For example, if the URL is SIP:aabade@cisco.com, enter aabade. Do not use spaces.
•Rows are numbered as a convenience. You can enter alternate extensions in any order, and you can have blank rows.
Step 3 Repeat Step 2 as necessary.
Step 4 Click the Save icon. Alternate extensions are enabled for all rows in the table.
To Modify or Delete Alternate Extension(s)
Step 1 In the Cisco Unity Administrator, go to any Subscribers > Alternate Extensions page.
Step 2 Do any of the following:
•To modify an extension, change the extension in the Alternate Extensions table.
•To delete extensions, check the check boxes next to the alternate extensions that you want to delete.
•To remove all alternate extensions listed in the table, click Select All.
Step 3 Click the Save icon.
Step 4 Repeat Step 2 and Step 3 as necessary.
Note You can run the Cisco Unity Bulk Import wizard when you want to add alternate extensions for multiple subscribers at once. When you do, the Cisco Unity Bulk Import wizard appends the new alternate extensions to the existing table of alternate extensions, beginning with the first blank row.
Alternate MWIs
You can set up Cisco Unity to activate alternate MWIs when you want a new message for a subscriber to activate the MWIs at up to 10 extensions. For example, a message left at extension 1001 can activate the MWIs on extensions 1001 and 1002.
Cisco Unity uses MWIs to alert the subscriber to new voice messages. MWIs are not used to indicate new e-mail, fax, or return receipt messages.
Setting Up Alternate MWIs
Cisco Unity can activate alternate MWIs. Note that depending on the phones and phone systems, some additional phone system programming may be necessary. Refer to the installation guide for the phone system.
To enable alternate MWIs for extensions, do the following procedure for each subscriber who needs alternate MWIs.
To Set Up Alternate MWIs for Extensions
Step 1 In the Cisco Unity Administrator, go to the applicable Subscribers > Subscribers > Messages page.
Step 2 Confirm that the Use MWI for Message Notification check box is checked.
Step 3 Click the Add button located beneath the MWI Extensions table to add a row to the table. By default, the first row in the table contains an "X" to indicate the primary extension assigned to a subscriber. If you want one more extension and do not need to activate the MWI on the primary extension, you can also modify the first row.
Step 4 Enter the applicable extension in the Extension field of the table. MWIs are automatically enabled for all rows in the table. When entering characters in the MWI Extensions table, consider the following:
•Enter digits 0 through 9. Do not use spaces, dashes, or parentheses.
•Enter , (comma) to insert a one-second pause.
•Enter # and * to correspond to the # and * keys on the phone.
Step 5 Click the Save icon.
Step 6 Repeat Step 3 through Step 5 as necessary.
Note You can run the Cisco Unity Bulk Import wizard when you want to set up alternate MWIs for multiple subscribers at once.
To change or delete alternate MWIs for extensions, do the following procedure.
To Modify or Delete Alternate MWIs
Step 1 In the Cisco Unity Administrator, go to the applicable Subscribers > Subscribers > Messages page.
Step 2 Do either of the following:
•To modify an extension, change the extension in the MWI Extensions table.
•To delete extensions, check the check boxes next to the rows that you want to delete in the MWI Extensions table, and then click the Delete button.
Step 3 Click the Save icon.
Step 4 Repeat Step 2 and Step 3 as necessary.
Appendix: PIMG Integrations Over a WAN That Use the G.729a Codec Must Disable Comfort Noise
When the PIMG units connect to a WAN and use the G.729a codec, you must disable comfort noise. Otherwise, callers will hear loud comfort noise after pressing a DTMF key or between prompts when recording a message.
To Disable Comfort Noise
Step 1 On the Cisco Unity server, on the Start menu, click Run.
Step 2 In the Run dialog box, enter regedit and click OK.
Caution Changing the wrong registry key or entering an incorrect value can cause the server to malfunction. Before you edit the registry, confirm that you know how to restore it if a problem occurs. (Refer to the "Restoring" topics in Registry Editor Help.) Note that for a Cisco Unity failover system, registry changes on one Cisco Unity server must be made manually on the other Cisco Unity server, because registry changes are not replicated. If you have any questions about changing registry key settings, contact Cisco TAC.
Step 3 If you do not have a current backup of the registry, save the registry settings to a file by doing the following depending on the Windows version:
Step 4 Expand the registry key
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Avaudio\Parameters
and double-click the ComfortNoise value in the right pane.Step 5 In the Edit DWORD Value dialog box, under Base, click Decimal.
Step 6 In the Value Date field, enter 128.
Step 7 Click OK.
Step 8 Exit the Registry Editor.
Step 9 Restart the Cisco Unity server.
Step 10 If you are using failover, repeat this procedure to apply the registry setting to the secondary Cisco Unity server.
