[NateCCIE]

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

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?
