Polycom 1500/1800/2000/4000 manual MCU Interoperability Table

Defining Cascading Conferences

Since the remote participant settings are unknown, it is recommended that the gateway or endpoint be configured to support a higher line rate (for example, 768 Kbps) to allow flexibility during endpoint capability negotiations.

MCU Interoperability Table

The following table lists the different MCU and Gateway configurations that are supported or implemented when routing Cascaded ISDN calls.
