[Kamailio-Users] Openser configured as outbound proxy - retransmissions issue.

[Siddhardha Garige]

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.

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.

regards
klaus

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.
