Only endpoints (UAs) can respond to session timer reinvites. Only endpoints can reject them with a 488. Kamailio just relays these requests and replies. -- Sent from my BlackBerry.

At the moment the the call fails after 15 mins. Related to this, another provider sends re-invites during a dialog to check that my kamailio is alive. However Kamailio responds with "488 not here". How do I process these as well? Asterisk sits behind Kamailio.
