I have a client that we setup UCA and have all the licensing needed. It is connected to a Mitel 5000 ver 6.0.120.0
Mas version is 5.0.116.0 and MSL version is 10.0.43. The issue they are experiencing is the softphone connects and they are able to make calls using the softphone but they are unable to receive calls. If you try calling the SIP extension, the pone locks up for a minute trying to call the phone and the your get destination not responding message. I have all the ports opened according to the engineering guidelines. They customer is using AT&T as a carrier and are using Iphones.


Any ideas? Thanks.
