Hello,
there should be no retransmission on TCP done by Kamailio.
I a look at time stamps, it is different than standard SIP retransmission intervals. Have you changed them in tm parameters?
We have these values:
root@ip-10-45-159-161:~# grep '"tm"' /usr/local/etc/kamailio/modules.cfg modparam("tm", "failure_reply_mode", 3) modparam("tm", "fr_timer", 30000) modparam("tm", "fr_inv_timer", 120000) root@ip-10-45-159-161:~#
As you say it is over wireless, might be the network driver doing some re-tranmissions.
No, that's not wireless at the server's end (which I guess you meant). It is wireless at callee client's LAN.
Also, ngrep is not always good at capturing big packets, so just seeing partial sip packets is ok as long as the receiving party doesn't complain of broken/incomplete sip packet.
I accept the chance that I misinterpret the output of ngrep. So I need to collect more info, like the traffic from client network.
Thank you very much for commenting.
