hi
our freeswitch server has to talk to a sonus ip-switch
when we want to setup a call we do get a "100 Trying" and then a "180 Ringing"
within the "180 Ringing" we get a sdp with "a=sendonly" then our freeswitch
quits with a CANCEL message.
i simply don't get why our freeswitch aborts the session - i think it would work
if no "a=sendonly" would be present in the sdp.
my technical contact doesn't want to switch 180 to 183 on the sonus side - this would
also work (i think). in fact he says that 180 ringing is vaild, he isn't that wrong in
this case.
our freeswitch works in proxy mode, we do use trunk 15396
