Hi Dave,
I was aware of that service parameter. Sadly, I don't think it can help in
this case. What I need would be something like "Continue routing on Q.931
Disconnect Cause Code" and giving it the cause code 27 in order to continue
routing.
Instead, I change the Stop Routing on Unallocated
Daniele, have you tried exploring the service parameter "Stop Routing on
Q.931 Disconnect Cause Code" at all? I'm not certain it will be useful in
your scenario, but if you haven't tried it, that may be an option for you.
It's under Service Parameters > select server > select Cisco CallManager >
