Re: [OpenSIPS-Users] repeated INVITE issue

Hello PlayMen,

Looks like you are replying with "100 Trying" after calling t_relay().
Can you reorganize the script so that the "100 Trying" is replied immediately after receiving the intitial INVITE?

sl_send_reply("100", "Trying");

This will hopefully prevent the sender from re-transmitting the INVITE at the first place.

Best Regards,
- Gary

Yes I do.

Here is part of my script:
  if ( t_check_trans() ) {
   xlog("L_ERR", "$fU: This INVITE is already received");
   exit;
  }

Hello,

are you using t_check_trans before t_relay to check if the second and third INVITEs are retransmission?

Regards.

It replies back with provisional response (100 - Ok giving a try), but a bit too late - after more than one invite has been received already.

The question is more why OpenSips sends 3 replies to the upstream provider instead just one since the invites are duplicates.

Hello,

check why OpenSIPs don't send provisional response to user that send 3 INVITEs or why the user don't receive these provisional responses.

Hello folks,

I have opensips (v1.11.3) running here. I am having the following problem:
Sometimes Opensips gets 3 INVITE's with the same From: tag ~0.5 seconds apart of each oother.
After executing t_relay() opensips sends 3 invites to the upstream provider.
What should I do to limit t_relay() of forwarding only one INVITE request?
This is how trace looks like:

              OpenSips
---- INVITE ----->
---- INVITE ----->
---- INVITE ----->
              t_relay
<--100 Give a Try--
                  ---- INVITE ----->
<--100 Give a Try--
                  ---- INVITE ----->
<--100 Give a Try--
                  ---- INVITE ----->

Best regards,

PlayMen
