Hello all,
I am working on configuring openser as a outbound proxy. User agents register to service provider through openser outbound proxy. I am experiencing issues with retransmissions.
Case 1.
UA sends an INVITE to Proxy and proxy is down. Openser sends 100 Trying to UA and retransmits INVITE messages to proxy. After 8 retry attempts sends 408 Request time out to handset. All as expected.
Case 2:
Openser received INVITE for UA from proxy. UA is down. Openser sent 100 Trying to proxy and routes reqest to UA. No response from UA and ** Openser did not send any retransmissions of INVITE to UA**. After a while CANCLE arrived at openser and cleared transaction.
why openser does retransmissions in Case 1 and why not in case 2?
Can openser proxy be operated in stateful outbound proxy to take care of retransmissions?
I am using default openser config file. Is there any thing I am doing wrong?
Any help is greatly appreciated.
Thanks Sid
Hi!
Openser should retransmit in both cases. Are you using t_relay in both cases? To find out what is going on set debug=4 and watch the logfile.

Klaus,
Yes, it does. Both client and openser were on same interface listening on different ports. Messages never showed up on wireshark for some reason. Openser debug and tcpdump did show them.
thanks again.
