Yes

Maximum Length of DNIS

The maximum length of an incoming Dialed Number Identification Service (DNIS). DNIS is a phone service that identifies the number a caller dialed. Your network dial plan has the information for the maximum length of DNIS. The number of DNIS digits from the PSTN must be less than or equal to the maximum length of DNIS field.

For example, if the Gateway dial pattern is 1800******, the value of Maximum Length of DNIS field should be 10.

Note 

If you are using the Correlation ID method in your ICM script to transfer calls to Unified CVP, the maximum length of DNIS should be the length of the label that is returned from ICM for the VRU leg of the call. When ICM transfers the call, the Correlation ID is appended to the label. Unified CVP then separates the two, assuming that any digits greater than maximum length of DNIS are the Correlation ID. The Correlation ID and label are then passed to ICM.

Dialed Number (DN) patterns

Patterns for sending calls to the originator -

Dialed Number (DN)

Creates a SIP Send Back to Originator Lookup Table. Specify the DN patterns to match for sending the call back to the originating gateway for VXML treatment. For the Unified CVP branch model, use this field to automatically route incoming calls to the Call Server from the gateway back to the originating gateway at the branch.

This setting overrides sending the call to the outbound proxy or to any locally configured static routes. It is also limited to calls from the IOS gateway SIP "User Agent" because it checks the User Agent header value of the incoming invite to verify this information. If the label returned from ICM for the transfer matches one of the patterns specified in this field, the call is routed to sip:<label>@<host portion of from header of incoming invite>.

Three types of DNs work with Send To Originator: VRU label returned from ICM, Agent label returned from ICM, and Ringtone label.

Send To Originator does not work for the error message DN because the inbound error message is played by survivability and the postroute error message is a SIP REFER. (Send To Originator does not work for REFER transfers).

Note 

For Send To Originator to work properly, the call must be originated by TDM and have survivability configured on the pots dial peer.

None

24 characters. See Valid Format for Dialed Numbers.

No

Patterns for RNA timeout on outbound SIP calls -

Dialed Number (DN)

Creates a DN pattern outbound invite timeout using the DN and timeout entered above the Add button. Click Add to add the newly created DN pattern outbound invite timeout to the list displayed in the box below the Add button.

Click Remove to delete the selected DN pattern outbound invite timeout from the list.

None

24 characters. See Valid Format for Dialed Numbers.

No

Timeout

The number of seconds the SIP Service waits for transferee to answer the phone or accept the call.

If a selected termination (for either a new or transferred call) returns a connection failure or busy status, or if the target rings for a period of time that exceeds the ring-no-answer (RNA) timeout setting of the Call Server, it cancels the transfer request and sends a transfer failure indication to Unified ICM. This scenario causes a router requery operation. The Unified ICM routing script then recovers control and has the opportunity to select a different target or take other remedial action.

60 seconds

5 to 60

No

Custom ringtone patterns -

Dialed Number (DN)

Specify a custom DN pattern. Click Add to add the newly created DN pattern to the list displayed in the box below the Add button.

To know which DN is configured on the gateway to play ringtone, execute the sh run command on the gateway and look for the dial peer that matches the incoming dialed number.

Note

Ring No Answer Settings with SIP

If you use the Unified CVP Ring No Answer (RNA) settings in SIP, ensure that the RNA value is lower than the Unified ICME Agent Desk Setting RNA timeout. The range of RNA value is from 5 to 60 seconds; the default value is 15 seconds.

Unified CVP makes a call to the ringtone service on the VXML gateway. This call is followed by sending the call to the Unified Communications Manager trunk for the agent. During this period, an agent has sufficient time to receive the delivered event after being reserved, and also ensures that Unified ICME reporting is correct in terms of handled time and RNA call disposition calls reporting.

Valid Format for Dialed Numbers

Valid dialed number patterns are the same as for the ICM label sizes and limitations, including the following:

  • Dialed numbers can be up to 24 characters.

  • Use the period (.) or the letter X for single-digit wildcard matching in any combination. Avoid using the letter "T" for wildcard matching.

  • Use the greater than (>), asterisk (*), or exclamation (!) character as a wildcard for zero or more digits at the trailing end of a dialing number.

  • The highest precedence of pattern matching is an exact match, followed by the most specific wildcard match. When the number of characters is matched equally by more than one wildcard pattern, precedence is given from top to bottom of the configured DN list.

IVR Service Settings

The IVR service creates VXML documents that are used to implement miroapplications based on Run Script instructions received by the ICM. The VXML pages are sent to the VXML Gateway to be executed. The IVR Service can also generate external VXML through the microapplications to engage the Unified CVP VXML Server to generate the VXML documents.

The IVR Service plays a significant role in implementing a failover mechanism. This capability is achieved without Automatic Speech Recognition (ASR)/Text To Speech (TTS) Server and VXML Servers. Up to two of each such server are supported, and the IVR Service orchestrates retries and failover between them.


Note
Configure the following servers before you configure the IVR service:

  • ICM Server

  • Media Server

  • ASR/TTS Servers

  • VXML Server

  • Gateway

To configure IVR settings on a Call Server, on the IVR tab, enter or modify the field values, as listed in the following table:

Device Pool

A device pool is a logical group of devices. It provides a convenient way to define a set of common characteristics that can be assigned to devices, for example, the region in which the devices are located. You can create device pools and assign devices to the device pools you created.

Every device you create is automatically assigned to a default device pool, which you can never remove from the selected device pool list. The Administrator account is also assigned to the default device pool automatically. Having the administrator account ensures that the administrator can view and manage all devices. You cannot remove the Administrator account from the default device pool.

When you create a user account, you can assign the user to one or more device pools, which allows the user to view the devices in those pools from the Control Center. Subsequently, you can remove the user from any associated device pools, which prevents that user from viewing the pool devices in the Control Center. Removing a user from the default device pool prevents the user from viewing all devices.

Add or Remove Device From Device Pool

Procedure
Step 1

From the Device Management menu, select a device to add to the Device Pool.

Example:
To add a Call Server to a device pool, select Unified CVP Call Server from the Device Management menu.

A window that lists known devices of the type you selected appears. For example, if you select Call Server, all the known Unified CVP Call Servers are listed.

Step 2

Select a device pool from the Device Pool list and click Edit.

Step 3

On the Device Pool tab:

  • In the Available list box, select one or multiple devices and click the Add arrow. The added devices appear in the Selected list box.
  • To remove the added devices from the Selected box, select them and click the Remove arrow. The added devices appear in the Selected list box.
Step 4

Click Save & Deploy.

Note 

  • Click Save to save the changes in Operations Console and add or remove a device from Device Pool later.

  • Some edit-device windows have an Apply button instead of Save. Click Apply to copy the configuration to the device.

Infrastructure Service Settings

The Call Server, Unified CVP VXML Server, and Reporting Server offer one or more services. The Call Server provides SIP, IVR, and ICM call services. The Unified CVP VXML Server provides VXML services, and the Reporting Server provides reporting services. Changes to Infrastructure settings affect all services that use threads, publish statistics, send syslog events, or perform logging and tracing. For example, when you change the syslog server setting, the changes are applied to all services that write to syslog.

License Thresholds

The three thresholds namely safe, warning, and critical describe the percentage of licenses that must be in use to reach their respective licensing state.

Crossing a threshold does not always mean the state changes. For example, if you have 100 licenses and the Safe, Warning, and Critical license thresholds are set to the defaults of 90%, 94%, and 97%, and 89 licenses are in use, licenses are at a Safe level. When the number of licenses in use reaches 94, the license state changes from Safe to Warning level. If one more license is used, the license state remains at the Warning level. If three licenses, which are no longer in use, are released, 92 licenses remain in use and the license state remains at the Warning level. After the licenses in use return to the previous threshold (90), the state changes from Warning to Safe.
