Multimedia Call Handling (MMCH)

Expansion Services Module

An Expansion Services Module (ESM) provides T.120 data sharing capability on a

MMCH multipoint H.320 video conference. Each conference participant must

have endpoints administered and a personal computer with the H.320 video

application installed. The S8700 Multi-Connect system must have the expansion

service module installed.

Troubleshooting

Before troubleshooting any problems associated with the S8700 Multi-Connect

MMCH, always be sure that the endpoint is operating correctly (audio, video, and

data) by making point-to-point test calls. If possible, make the test calls over the

network to test the connectivity and routing of network calls from the endpoint.

This eliminates problems such as disconnected audio or video cables and

network troubles.
