Hi, All! Hopefully someone can point me in the right direction. I have a Mitel SX2000 Light that I am interfacing with my Asterisk box over a T1. I can receive calls on the Asterisk box without any problems, but when I call an extension on the Mitel, I heard the ringing from the IP phone, but I don't see anything on the Mitel, other than channel 1 of the T1 showing as "Locked Out." As soon as I hang up, the T1 channel goes back to idle. Any help some could offer would be greatly appreciated! James -------------- next part -------------- An HTML attachment was scrubbed...
