[Spce-user] Call does not stop after hang-up

Hi Adrew!

I captured it with sngrep tool.
I'm using "WireShark Version 2.4.3 (v2.4.3-0-g368ba1ee37)" and I can open it without problems. I don't know what is wrong.

Thank  you!

Hi Marcos,
yes, this is the problem and most probably it's caused by wrong route or contact headers from the end device.
Unfortunately, I still can't open the new pcap file you've provided ("The capture file appears to be damaged or corrupt.
(pcap: File has 823214080-byte packet, bigger than maximum of 262144)") How did you capture it? Did you press Ctrl+C to stop capture before copying the file from your machine?
Anyway, I would suggest to check the headers, especially in the 200 OK received from callee. There must be something wrong.

Also, as a generic hint sometimes it helps activating topology stripping feature (set kamailio.lb.security.topos.enable: 'yes' in config.yml if you are on mr6.5.x release) because then we are stripping the rec-route headers. But it will not help with bad INVITE or 200 from the UA.

Hope this helps,
