[SR-Users] Re-invites from carrier breaks the call

[Will Ferrer]

Hi All

We have any issue with re invites coming from the carrier.

When a reinvite occurs, our softphone client gets the invite, sends a 100,
and then sends 200 ok. However the 200 ok does not have the softphones ip
in the record route. Since it's not in the record route the ack from the
carrier never makes it's way all the back to the softphone.

This causes the softphone to keep sending 200 oks since it never gets the
ack.

Eventually the softphone gets tired of sending 200 oks and sends a bye.

Is there any way that Kamailio can help me correct for this, or do we need
to have our clients use different softphones? If it has to be handled via
softphones is there even a softphone that can account for this?

Thanks for all your assistance in advance.

All the best.

Will Ferrer
