Send the network dumps with INVITE/1xx/200/ACK messages. I will take a
look at them. It may be a problem related to the tags or other SIP
parameters so the gateway rejects the ACK.
Also, if you can provide more details about, it may be helpfully -- what
gateway, have you tried same scenario with other SIP clients ...

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
