This is going to be tricky to explain without diagrams! This is what we want:
Box1 is a CME with extensions 3xx
Box2 is connected to global CUCM with extensions 8xx
Need to be able to dial 3xx from Box2 and 8xx from Box1. Have created dial-peers on both boxes and can dial 8xx from CME side. Phone rings but when answered there is no audio and the off-hook signal is not sent to the calling party. Same for other way round.
We've got this working between two CME boxes so sure the config is correct. The problem is we don't have access to the CUCM so would like to be able to completely ignore it when dialling 3xx from box2.
Thanks, if further info needed please let me know.
