Hello,

the BYE is missing the Route header. Even if it looks like doing strict routing instead of recommended loose routing, the BYE must have a Route header with the contact address in INVITE or 200ok, depending whether the BYE is sent by callee or caller.

Cheers,
Daniel

Hello,
I am currently going through an Inter-Op test with a new carrier and there have been some issues. I have my Kamailio server integrated with many tier-1 carriers, so I'm pretty sure I'm doing everything OK. The problem is in the BYE coming from the ITSP, the URI isn't valid, but I am not sure based on RFC3261 exactly why it isn't correct. If anyone can take a quick glance, I would really appreciate it.

Thanks!
