IP Video Telephony Configuration

This topic provides an overview of how IP Video Telephony was configured for Cisco IP Communications Release 5.1(1) testing. This topic does not include detailed installation and configuration instructions. Rather, it is intended to provide you with guidance and serve as a reference as you set up video devices in your IP telephony solution.

For additional information and guidelines for implementing Cisco IP Video Telephony, refer to the documents listed Table 12-1.You can also refer to documentation provided by the vendors of Tandberg video endpoints and Polycom video endpoints.

1. PSTN = public switched telephone network.

Note Cisco Unified CallManager 5.1 supports security on the Cisco Unified IP Phone 7940G/7941G/7960G/ 7961G/ 7970G/7971G running SCCP. These phone models also have video capabilities when associated with Cisco Unified Video Advantage. If two securevideo-capableendpoints call each other, the SCCP signaling and audio media path will be encrypted. Video will work, however signaling and the video media path to Cisco Unified Video Advantage will not be encrypted.

Call Routing

The IP Video Telephony deployment supports the following call routings. SCCP endpoints include SCCP Tandberg T1000, and Cisco Unified Video Advantage associated with Cisco IP Phone models 7940G/7960G/7970G. H.323 endpoints include H.323 Tandberg T1000 and Polycom VSX 7000.

SCCP endpoint > Cisco Unified CallManager > SCCP endpoint

H.323 endpoint > Gatekeeper > Cisco Unified CallManager > SCCP endpoint

SCCP endpoint > Cisco Unified CallManager > Gatekeeper > H.323 endpoint
