IP trunks

[testLED]

Ok any idea's

IP trunk group set up and seems to work. one site can dial the other but when they try to dial back on the trace it grabs the trunk group and trunk member but denial event 1220 appears. It makes no different on the codec set its still the same. Both sig groups all look ok.

Check your signaling group on the side that won't dial out and connect to verify you have the trunk group in the "Trunk Group for Channel Selection" field.
