I have a SIP trunk between the CUCM and the Mitel that isn't quite functional. From the Cisco I can talk and the Mitel side will hear me but I can't hear anything from the Mitel side. I have trunking information setup on both side pointing to each other. I am not sure what info I should provide, just let know know what information you need and i will get it.
