which version of opensips are you using ? I'm not aware of retransmission after a final reply or timeout.
if you can provide a config to replicate the issue or logs of opensips we might able to check more

 I set fr_timeout parameter of tm module to 5, so after 5 seconds opensips generates a 408 response, but keeps retransmitting the INVITE even after that.Apart from that the handling of INVITE is pretty straight forward:Do lookup to find the destination (callee), and if found call t_relay().Thanks

Hi Yuval,
SIP Timers related functions can be found in TM (transaction) module http://www.opensips.org/html/docs/modules/2.4.x/tm.html
hard to say whats causing retransmission after a final reply without knowing your config.

 Hi,1. How can I control the amount/time window of retransmissions?2. I see a behavior in which opensips sends an INVITE to a non responsive client. After a few retransmissions it sends a 408 to the originator of the INVITE, and then sends some more retransmissions of the INVITE. I don't understand why it send INVITE-s after the 408.
