Telephony Integration

Telephony Integration is a process that enables the communication between Cisco Unity Connection and the phone system, providing access to various features such as:

  • Calls to a user extension that does not answer are forwarded to the personal greeting of the user.
  • Messages left for a user activate the message waiting indicator (MWI) on the extension.
  • A user has easy access to messages by pressing a button on the phone and entering a password.
  • Calls to a user extension that is busy are forwarded to the busy greeting of the user.
  • Unity Connection receives caller ID information from the phone system (if available).
  • Unity Connection identifies the user who leaves a message during a forwarded internal call, based on the extension from which the call originated.

To know more about integrating Unity Connection with phone system, see the “Integrating Cisco Unity Connection 10.x with the Phone System” chapter of Design Guide for Cisco Unity Connection , Release 10.x, available at http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/design/guide/10xcucdgx/10xcucdg050.html .

After understanding how the Unity Connection integrates with a phone system, you need to configure and edit the settings for phone system, ports, port group, trunk, and security in Unity Connection.

To configure telephony integration in Unity Connection, see the following sections:

Phone System

Cisco Unity Connection Administration identify multiple phone systems that integrate Unity Connection with Cisco Unified Communications Manager. For a matrix of supported combinations, see the Multiple Phone System Integration Guide for Cisco Unity Connection at http://www.cisco.com/en/US/products/ps6509/products_installation_and_configuration_guides_list.html .

A phone system has one or more port groups that further have voice messaging ports.


Note Cisco Unified Communications Manager Business Edition (CMBE) does not support adding or deleting phone system integrations.


Configuring Phone System Integration

The settings for a phone system can be modified after it is integrated with Unity Connection. The phone system settings identify the phone system with which Unity Connection integrates and regulate certain phone system features. (Integration configuration settings are located in the port groups that belong to the phone system.)

You can delete a phone system if it is no longer used by Unity Connection. Before a phone system is deleted, make sure to delete or reassign all of the following objects that are associated with the phone system to another phone system:

  • All users (including MWI devices and notification devices)
  • All user templates
  • All system s
  • All call handler templates

To Configure a Phone System in Unity Connection


Step 1 In Cisco Unity Connection Administration, expand Telephony Integrations and select Phone System .

The Search Phone System page displays the currently configured phone system integrations.


Note The port count is zero for the newly configured phone systems. After adding ports to the specific phone system, the port count shows the number of available voice ports.

Phone System Associations

You can view the list of all Unity Connection users associated with the phone system by selecting the Phone System Associations option on the Edit menu of Phone System Basics page.

Port

The voice messaging ports allow Unity Connection to receive calls (for example, to record a message) and make calls (for example to send message notifications or to set MWIs).

Each voice messaging port belongs to only one port group. Port groups have their own voice messaging ports.


Note Ports are no longer licensed in the Unity Connection server. The ports are now configurable as per the hardware of the server deployed for installing Unity Connection.


Configuring Ports

Voice messaging ports provide the connections for calls between Unity Connection and the phone system. You can add voice messaging ports after the phone system has been created.

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

This section includes information on configuring a port group for Unity Connection, define the settings for the ports, and save them.

Port Group

Port Groups are assigned voice messaging ports that define Unity Connection integration configuration settings. Most of the phone system integrations need only one port group. However, you may need multiple port groups in the following scenarios:

  • For integration 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.

Cisco Unified Communications Manager Business Edition (CMBE) only: Before you can add a port group, you must have the existing voice messaging ports in Cisco Unified CM Administration, which do not belong to a port group.


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


You can change the settings of a port group, which affects only the voice messaging ports of that port group. When you delete a port group, any voice messaging port belonging to that port group are deleted at the same time. However, the phone system to which the port group belongs is not deleted.

Audio and Video Format Using Phone

Cisco Unity Connection advertises the audio format (or codec) that is preferred for the media stream with the phone system.

Consider the following when setting the audio format:

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

For more information on audio format codecs, see the “Audio Codecs” section in the “Sizing and Scaling Cisco Unity Connection 10.x Servers” chapter of the Design Guide for Cisco Unity Connection http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/design/guide/10xcucdgx/10xcucdg025.html#pgfId-1071095 .

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 the 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 the 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.

For instructions on enabling and configuring IPv6 for an existing Cisco Unified CM integration, see the “Upgrading Cisco Unity Connection” chapter in Install, Upgrade, and Maintenance Guide for Cisco Unity Connection, Release 10.x, available at www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/install_upgrade/guide/10xcuciumgx/10xcuciumg030.html .
