[cisco-voip] Disconnect of calls when switching to SRST

[Erick Bergquist]

I had someone lose some active calls on PRIs (MGCP
Controlled) when brief network issues caused the
gateways to unregister and re-register. On 3700s with
recent 12.3T IOS. Router is doing fallback also. I am
looking at gateway IOS level and awaiting test window
and verifying config is good, but anyone seen this
before? The exact symptons of cause of network issues
is unknown but in past i'm being told active calls
weren't dropped when gateway unregistered and went
into fallback.
