Hello,
There is something missing in your configuration file. See econfig
example from version 1.3 (etc/openser.cfg, line 214). You should add
something like this on the else branch for in dialog requests:
if (is_method("SUBSCRIBE|NOTIFY") && ($rd == "your.server.ip.address"|
$rd=="xmpp-gw"))
{
# in-dialog subscribe requests
route(2);
exit;
}
The way you have it now, all in dialog requests are not allowed, that is
all Notifies and the in dialog Subscribes.
regards,
Anca Vamanu
