Hello everyone!
We're using some Chinese GPON CPE with SIP clients in it with OpenSIPS
2.2.3 as a server, and we're having a problem: after successful REGISTER
client starts SUBSCRIBE process for event "message-summary", and after
authorization pass, server sends NOTIFY with "Event: message-summary",
but client respond to it with "SIP/2.0 400 Missing or invalid
message-summary" message.
On which side is error?
In opensips.cfg SUBSCRIBE is handling by this part:
if (is_method("SUBSCRIBE") {
route(handle_presence);
}
....
route[handle_presence]
{
if (!t_newtran())
{
sl_reply_error();
exit;
}
if(is_method("PUBLISH"))
{
handle_publish();
}
else
if( is_method("SUBSCRIBE"))
{
handle_subscribe();
}
exit;
}
Here's dump of SIP messages:
