Cisco Unified Communications Manager Integration Methods (For Cisco Unified CM Versions 4.x and 5.x)

This chapter describes the steps required to integrate Speech Connect with Cisco Unified Communications Manager (CM) (formerly known as Cisco Unified CallManager), versions 4.x and 5.x.

See the following sections:

•Integrating with Cisco Unified Communications Manager Version 4.x

•Integrating with Cisco Unified Communications Manager Version 5.x

Integrating with Cisco Unified Communications Manager Version 4.x

This section describes the telephony integration of Speech Connect with Cisco Unified Communications Manager version 4.x, including support for blind call transfers. For Cisco Unified CM version 4.x, which does not support SIP supplementary services, an intermediary gateway is required for integration to the Speech Connect server. The two supported methods of integration are:

•TIMG Configuration

•PIMG Configuration

TIMG Configuration

Description

Figure 10-1 shows an example of a TIMG integration.

Figure 10-1 TIMG Integration

In this example, Speech Connect communicates with a TIMG telephony gateway by using SIP. The telephony gateway is integrated to Cisco Unified CM by using a T1 PRI running the QSIG protocol for supplementary services, including blind transfers. QSIG path replacement is used to eliminate call hair-pinning across the T1. Call party information is transmitted across the T1 via QSIG signaling.

Components

The following components are used in the TIMG configuration:

•Cisco Unified CM version 4.2

•Cisco 2811 ISR with a VWIC-1MFT-T1

•Dialogic Media Gateway DMG2030DTI (TIMG300DTI)

•Cisco Speech Connect

Procedures

Do the following procedures in the order presented to integrate Speech Connect with Cisco Unified CM version 4.x:

•To Configure Cisco Unified Communications Manager and the Voice Gateway for MGCP Digital T1 Integration

•To Configure the Dialogic Media Gateway

•To Configure the Telephony Settings on the Dialogic Gateway

PIMG Configuration

Description

Figure 10-2 shows an example of a PIMG integration.

Figure 10-2 PIMG Integration

In this example, Speech Connect communicates with a PIMG telephony gateway by using SIP. The telephony gateway is integrated to Cisco Unified Communications Manager by using analog telephony ports. Call transfers are supported via hookflash operation. Due to the analog nature of this integration, an SMDI serial link is required in order for Cisco Unified CM to pass call party information.

Components

The following components are used in the PIMG configuration.

•Cisco Unified CM 4.2

•Cisco 2811 ISR with a VIC-4FXS

•Dialogic Media Gateway DM1008LS (PIMG80LS)

Procedures

Do the following procedures in the order presented to integrate Speech Connect with Cisco Unified CM version 4.x:

•To Configure the ISR Gateway for MGCP Analog Ports

•To Configure the Dialogic Media Gateway

•To Configure the Telephony Settings on the Dialogic Gateway

To Configure the ISR Gateway for MGCP Analog Ports

Because Speech Connect must receive both DNIS (called party) and ANI (calling party) to operate efficiently, all calls to the server must be a result of a call-forwarding situation in Cisco Unified CM. This is accomplished through the use of a restricted partition, calling search space, and CTI route point.

For example:

•Phone A with a "Phones" calling search space dials the Speech Connect pilot number 5555.

•Cisco Unified CM routes the call to a CTI route point that has a DN of 5555 in the "Phones" partition.

•The CTI route point DN 5555 is set to forward all calls to 5555 by using the "PIMG" calling search space.

•Cisco Unified CM routes the call to the route pattern 5555 in the "PIMG" partition and the call is sent to the Speech Connect server.

•Because 5555 in the "PIMG" partition corresponds to the Voice Mail DN and Voice Mail DN Partition configured in the SMDI service parameters, Cisco Unified CM sends the SMDI information to Speech Connect along with the call.

Note Although multiple route patterns can be routed to Speech Connect, only one number will support integration information, due to the SMDI limitations within Cisco Unified CM version 4.x. All other calls to Speech Connect will be sent without integration information and answered by the default Speech Connect application. Heuristic dialing will also not be available for these calls.

Step 1 Complete the steps outlined in the "Configuring Cisco CallManager with IOS MGCP Gateways (Analog FXO, FXS Ports)" document, available at http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a008009428e.shtml.

Step 2 Configure the restricted PIMG partition.

Step 3 Configure the PIMG calling search space.

Step 4 Configure the Speech Connect CTI route point.

Step 5 Configure the Speech Connect route pattern.

Step 6 Configure the SMDI service parameters.

Step 7 Configure the restricted PIMG partition:

Integrating with Cisco Unified Communications Manager Version 5.x

This section describes a SIP integration with Cisco Unified Communications Manager version 5.x with support for blind call transfers.

When Cisco Unified CM version 5.x supports SIP supplementary services, the Speech Connect server integrates directly to Cisco Unified CM by using a SIP trunk.

Description

Figure 10-3 shows an example of SIP integration.

Figure 10-3 SIP Integration

In this example, Speech Connect communicates directly with Cisco Unified CM via SIP. Blind transfers are performed by using the SIP REFER method. Call party information is all contained within the SIP messages.

Procedures

The following procedures are required to configure a SIP trunk on Cisco Unified CM version 5.x to integrate with a Speech Connect server. Do the following procedures in the order shown:
