I have a route pattern going to a route list that has a PAETEC SIP trunk in a group and then a H323 gateway in a route group so that calls to the pattern will be directed toward the pots lines on the H323 Gateway if I cannot make calls out the SIP trunk. What's not happening is that when I shut down the ethernet interface that the SIP trunk is on, make a call, the CCM or CUBE? does not failover to try and make the call out the POTS lines defined on the H323 gateway. If I swap the order of the Route groups to have the call go out the H323 first and unplug all my POTS line the call will failover to and go out the SIP trunk. I may not be emulating a downed sip trunk by just shutting down the interface that the SIP trunk is pointing to?? Anyone know how I can test the failover from the SIP trunk to the H323 POTS lines? Or is there some sort of timer that I can set to make it faiover to the POT lines when the SIP trunk is not available.
