Check if you do not have SDP in your ACK. Your gateway might not understand it.

Hi..i have a problem with my grandstream phones..When I try to make a call to a PSTN gateway the call disconnects after 15-20 seconds.But when I make a call between two grandstreams or between an ata 186 and a grandstream it is ok.I used ngrep to capture packets and it seems to be something about how the ACK is transmited between the grandstream and the gateway.The ACK is ok in the other cases.What seems to be the problem ?.
Thanks
