I have a problem with CME (on 2811 and on UC500) with Quescom gsm gateway, all work fine but when I place a call to a mobile I don't hear ringback tone until mobile phone start to ring (4-6 sec), I mean that I don't hear progress ringback tone.
It seems (but I'm not sure) that QuesCom gateway does not handle 183 Progress messages and support 180 Ringing with SDP.
Can anybody know the problem or have any solutions?
