mgcp srst fallback behavior

[J_Vansen_S]

Hi all, 

I have MGCP gateway with SRST configured, when it loses connectivity with the primary and backup CUCM, what would happen?

Does the gateway fall back to H323 protocol for further call processing by default?

Or does the gateway continues with the MGCP call processing without any interruption.

Mgcp requires at least one call agent to be active, so when both cucm servers are not reachable then mgcp will not work. SRST will take over and use h323 logic.

Hi,

MGCP will not work if the connectivity between GW and CUCM goes down.

The GW should have command "call-manager fallback-mgcp" and dial peers configured for it to work as H323 when the connectivity goes down.
