I am using an MGCP gateway with a PRI. The users can forward their phone off site fine with the exception of T-Mobile cellular calls. If they attempt this, they caller just gets a fast busy. Has anyone had this issue?Thanks
All looks well on the debug....I can see the proper digits being dialer, the call seems to proceed then disconnects. I assume it is something in the set-up message that the Cell carrier does not agree with.
