That was my initial thought as well, but I could  only see how to setup a route group with H.323/QSIG,MGCP, etc, not SIP.


I’ll look again.

Split it to two different trunks and add them both to a route group that is configured for round robin to the route list.

We have two cisco ISR 4331 Cube gateways in two different locations. I want to be able to route calls to both devices (preferably round-robin). I have the router pattern going to a trunk with both cubes defined (with sip options keep-alive configured). The issue we are having is that if the call is made to CUBE1 and the associated outbound dial-peer in in busyout, the CUBE returns 503  Service unavailable and CUCM doesn’t try CUBE2. What am I missing?
