I have a user that has their DID at one location that is forwarded to an off-node extension at a second location, where his office is located (long story). At the second location, I have enabled Dynamic Extension Express to ring both at his desk and his cell. All of that works ok. But he claims that when he answers the call on his cell, he gets disconnected after 5 to 10 minutes (I'm guessing the latter) ever time. I suspect this is some timer somewhere but I'm not sure which one.
