I undertstood from Mr. Graham (of Cisco) that the MGCP fallback feature will come about in the soon-2-b-released 12.2.11T IOS , whereby it allows
an MGCP Gateway to become H.323 when the CallManager is unavailable, which in turn allows SRST to utilize the gateway.
I have the following query i hope to be enilghten on :
1. SRST is invoked when the WAN link goes down, and the GW is thus unable to get a respond from the CCM. Hence, all IP Phone would fallback to the SRST gateway as a tentative "CM". MGCP supports redundancy when
the primary CCM goes down, the standby/backup CCM will be used instead.
As MGCP will be incorporated in2 the latest IOS, in the scenario whereby the
primary CCM goes down (& NOT the WAN link), should'nt it fallback onto the standby/backup CCM instead, rather than allowing the H.323 SRST to be invoked & taking over the role ?
So when will SRST be invoked then ? only when there are neither responses from the primary & backup CCMs, &/or when the WAN link is down..?

If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
