That is a really good question Matthew. It's been one I've had and put on the back burner for awhile. So here's what I "think" based on the docs and poking around in config.
________________________________________________________________________ ______________________ http://www.cisco.com/en/US/tech/tk1077/technologies_configuration_exampl e09186a008012ecc6.shtml >From the above doc link: R(config)#application R(config-app)#global R(config-app-global)#service alternate Default (H.323 is the default signaling protocol) ________________________________________________________________________ _____________________________ >From a lab router (ignore the hostname): CUBE(config)#application CUBE(config-app)#global CUBE(config-app-global)#service alternate ? dsapp ipsla-responder clid_authen clid_col_npw_npw AFW_THIRD_PARTY_CC CALLIndSs_SErviCe Default RetrProxy CTAPP clid_authen_col_npw fax_hop_on ipsla-testcall app-b-acd-aa clid_authen_npw session app-b-acd clid_authen_collect clid_col_npw_3 WORD Name of the alternate service ________________________________________________________________________ ____________________________________ So it looks like the command "ccm-manager fallback-mgcp" without the commands we're wondering about Will implicitly cause the router/gateway to fallback to H.323. With the command it explicitly Causes fallback to H.323. The reason for the command in question even existing seems to be based on the ability to fallback to an Application other than the default (H.323). "service alternate XXXXXXXXXX". Your thoughts?

Looking through Cisco documentation, I see the following snippet from time to time: application global service alternate Default In my studies the past year, I have never used those commands and my testing has always worked as expected. Typically, I will configure the following: mgcp mgcp call-agent 10.10.210.11 service-type mgcp version 0.1 mgcp dtmf-relay voip codec all mode out-of-band no mgcp timer receive-rtcp mgcp bind control source-interface Loopback0 mgcp bind media source-interface Loopback0 ! ccm-manager switchback immediate ccm-manager fallback-mgcp ccm-manager redundant-host 10.10.210.10 ccm-manager mgcp ccm-manager music-on-hold HQ-RTR#show ccm-manager fallback-mgcp Current active Call Manager: 10.10.210.11 MGCP Fallback mode: Enabled/OFF Last MGCP Fallback start time: None Last MGCP Fallback end time: None Can anyone shed light on the commands I mentioned at the beginning of this email? I understand that the command is supposed to let MGCP transition into H.323 and terminate the L3 backhaul to CUCM. But does it actually work and is it actually required?
