MGCP fallback to SRST different IOS commands

[hamed1900]

Hi All,

To enable fallback from MGCP to SRST there are different commands, I think they are different based on IOS Version, can someone explain the differnce.

1- ccm-manager fallback-mgcp

2- Application

    Global

     Service Alternate Deafult

3- call-manager-fallback

Thank you,

Hamed

The first two are related to the mgcp-fallback process. The third item you listed is separate and used for Cisco IP phones to failover to SRST. MGCP fallback is entirely separate from the SRST process; however, both will rely on the dial-peers of the router to route calls during the outage.
