Our Kamailio statefully forwards requests to our Asterisk cluster.
Sip session timers fail, whether our Asterisk servers are UAS or UAC.
Kamailio receives the re(INVITE), and just dispatches it out using the default algorithm.
I see the record-route header, so I’m not sure what else is missing..
(aside from the last sip packet showing the packet dispatched to a new asterisk peer)
Anybody have some troubleshooting tips for us?
Loose_route should match the transaction based on record-route, is my understanding.
Same thing happens whether carrier re(INVITE)’s or Asterisk does. Just gets dispatched to the next peer in the list.
