Managing Port Groups in Unity Connection

Port groups hold most of the integration configuration settings and some or all of the voice messaging ports for Unity Connection.

While most phone system integrations need only one port group, multiple port groups may be needed in the following circumstances:

  • For integrations with phone systems through PIMG/TIMG units, each PIMG/TIMG unit is connected to one port group with the applicable voice messaging ports. For example, a system that uses five PIMG units requires five port groups, one port group for each PIMG unit.
  • For integrations with other phone systems, an additional port group with its own voice messaging ports may be used for testing a new configuration or for troubleshooting.

Unity Connection port groups provide flexibility for integration configuration settings that apply to different sets of ports.

Adding a Port Group

You can add multiple port groups, each with its own integration configuration settings and its own voice messaging ports. In Unity Connection 10.0(1), in case of video calls, only SIP integration mode is supported.

Cisco Business Edition only: Before you can add a port group, you must have existing voice messaging ports in Cisco Unified CM Administration that do not belong to a port group.

Other configurations: For integrations with phone systems through PIMG/TIMG units, one port group is required for each PIMG/TIMG unit. For example, a system that uses five PIMG units requires five port groups, one port group for each PIMG unit.

NoteUnity Connection enables you to create a maximum of 90 port groups if you are using only TUI (touchtone conversation) and VUI (voice-recognition) features of Cisco Unity Connection. However, if you are using all the features of Unity Connection, you are allowed to create a maximum of 60 port groups.

Steps to Add a Port Group in Unity Connection

Step 1 In Cisco Unity Connection Administration, expand Telephony Integrations , then select Port Group .

Step 2 On the Search Port Groups page, under Port Group Search Results, select Add New .

Step 3 On the New Port Group page, enter the applicable settings and select Save .

 

Deleting a Port Group

When you delete a port group, any voice messaging ports that belong to it are deleted at the same time, but the phone system that the port group belongs to is not deleted.

Steps to Delete a Port Group in Unity Connection

Step 1 In Cisco Unity Connection Administration, expand Telephony Integrations , then select Port Group .

Step 2 On the Search Port Groups page, under Port Group Search Results, check the check box next to the port group name of the port groups that you want to delete.

Step 3 Select Delete Selected .

Steps to Change Port Group Settings in Unity Connection

Step 1 In Cisco Unity Connection Administration, expand Telephony Integrations , then select Port Group .

Step 2 On the Search Port Groups page, select the display name of the port group for which you want to change the settings.

Step 3 On the Port Group Basics page, change the applicable settings and select Save .

 

Changing the Audio Format that Unity Connection Uses for Calls

For calls, Unity Connection advertises the audio format (or codec) that is preferred for the media stream with the phone system. You should consider the following when setting the audio format:

  • For the following reasons, Unity Connection should use the same audio format for the media stream that the phone system uses:

– To reduce the need for transcoding the media stream from one audio format to another.

– To minimize the performance impact on the Unity Connection server and on the phone system.

– To preserve the audio quality of calls.

  • When Unity Connection advertises a different audio format than the one used by the phone system, the phone system transcodes the media stream.

To Change the Audio Format Used for Unity Connection Calls

Step 1 In Cisco Unity Connection Administration, expand Telephony Integrations , then select Port Group .

Step 2 On the Search Port Groups page, select the first port group that belongs to the phone system integration for which you want to change the audio format of the media stream.

Step 3 On the Port Group Basics page, on the Edit menu, select Codec Advertising .

Step 4 On the Edit Codec Advertising page, select the Up and Down arrows to change the order of the codecs or to move codecs between the Advertised Codec box and the Unadvertised Codecs box.

If only one codec is in the Advertised Codecs box, Cisco Unity Connection sends the media stream in that audio format. The phone system transcodes if it does not use this audio format.

If two or more codecs are in the Advertised Codecs box, Unity Connection advertises its preference for the first codec in the list but sends the media stream in the audio format from the list that the phone system selects.

Step 5 Select Save .

Step 6 (All integrations except SCCP) If you want to change the packet size that is used by the advertised codecs, on the Port Group Basics page, under Advertised Codec Settings, select the applicable packet setting for each codec and select Save .

Step 7 Select Next .

Step 8 Repeat Step 3 through Step 7 for all remaining port groups that belong to the phone system integration for which you want to change the audio format of the media stream.

 

Changing the Video Format that Unity Connection Uses for Calls

For calls, Unity Connection advertises the video format (or codec) that is preferred for the media stream with the phone system. You should consider the following when setting the video format:

  • When Unity Connection advertises a different video format than the one used by the phone system, the phone system transcodes the media stream.
  • Unity Connection should use the same video format for the media stream that the phone system uses for the following reasons:

– To reduce the need for transcoding the media stream from one video format to another.

– To minimize the performance impact on the Unity Connection server and on the phone system.

– To preserve the video quality of calls.

NoteIn Unity Connection 10.0(1) and later releases, only G.711 mu-law video format (or codec) is supported to record and play video greetings.

To Change the Video Format Used in Unity Connection Calls

Step 1 In Cisco Unity Connection Administration, expand Telephony Integrations , then select Port Group .

Step 2 On the Search Port Groups page, select the port group that belongs to the phone system integration for which you want to change the video format of the media stream.

Check this check box so that users can use the port for recording and playback through the phone in Unity Connection web applications. Assign Allow TRAP Connections to the least busy ports.

Outgoing Hunt Order

(not available for SIP integrations)

Enter the priority order in which Unity Connection uses the ports when dialing out (for example, if the Perform Message Notification, Send MWI Requests, or Allow TRAP Connections check box is checked). The highest numbers are used first. However, when multiple ports have the same Outgoing Hunt Order number, Unity Connection uses the port that has been idle the longest.

Security Mode

(available for Cisco Unified CM SCCP integrations only)

Select the applicable security mode:

    • Non-secure —The integrity and privacy of call-signaling messages are not ensured because call-signaling messages are sent as clear (unencrypted) text and are connected to Cisco Unified Communications Manager through a non-authenticated port rather than an authenticated TLS port. In addition, the media stream is not encrypted.
    • Authenticated —The integrity of call-signaling messages are ensured because they are connected to Cisco Unified CM through an authenticated TLS port. However, the privacy of call-signaling messages are not ensured because they are sent as clear (unencrypted) text. In addition, the media stream are not encrypted.
    • Encrypted —The integrity and privacy of call-signaling messages are ensured on this port because they are connected to Cisco Unified CM through an authenticated TLS port, and the call-signaling messages are encrypted. In addition, the media stream is encrypted.

IPv6 in Unity Connection (Cisco Unified Communications Manager Integrations Only)

Unity Connection supports IPv6 addressing with Cisco Unified Communications Manager phone system integrations using SCCP or SIP.

IPv6 support is disabled by default. When you enable IPv6, you can configure Unity Connection to obtain an IPv6 address either through router advertisement, through DHCP, or by manually configuring an address. You can also configure the mode in which Unity Connection listens for incoming traffic—IPv4, IPv6, or both IPv4 and IPv6.

For SCCP integrations with Cisco Unified CM, if Unity Connection is configured to listen for incoming IPv4 and IPv6 traffic, you can configure the addressing mode that Unity Connection uses for call control signaling for each port group to use either IPv4 or IPv6. (This mode is also used when connecting to a TFTP server.)

For SIP integrations with Cisco Unified CM, if Unity Connection is configured to listen for incoming IPv4 and IPv6 traffic, you can configure the addressing mode that Unity Connection uses for call control signaling for each port group to use either IPv4 or IPv6. (This mode is also used when connecting to a TFTP server.) In addition, you can configure the addressing mode that Unity Connection uses for media for each port group to use either IPv4 or IPv6.

Note the following considerations when deploying IPv6 for Cisco Unified CM integrations:

  • IPv6 is supported in Cisco Unified CM release 7.1(2) and later.
  • The CTL file required for security features (authentication and encryption) for SCCP integrations uses IPv4 addressing. Therefore, in order to use authentication and encryption with SCCP secure ports, you must retain the IPv4 address or host name for the Cisco Unified CM server(s) on the port group in Unity Connection.
  • Some versions of Cisco Adaptive Security Appliance (ASA) do not support application inspection for IPv6 traffic for Unified Communications application servers and endpoints. We recommend not using IPv6 for Unified Communications if you are using a Cisco ASA version that does not provide this support. See the documentation for your version of Cisco ASA to determine whether application inspection is supported in your deployment.
