call disconnects as soon soon as i answer
« on: November 08, 2017, 04:39:09 AM »
hello guys. I am deploying a gx2160 attached to a cisco call manager express with a sip trunk to voip.ms. This is the first grandstream phone in the environment. The rest are cisco phones. As soon as grandstream answers the call, the phone disconnects. Has any one experienced this or know how to rectify the settings on the grandstream.
