[Sylvester Nielsen]

Thank you very much. That was exactly the issue. Peer found the script which removed the route and after that it worked like a charm. :)

The problem is incorrect BYE from the callee at 212.98.66.168:

BYE sip:ngcp-lb at 87.116.27.246:5060;ngcpct='sip:127.0.0.1:5080' SIP/2.0
Via: SIP/2.0/UDP

It is completely missing the Route headers that should be:

Route:
<sip:87.116.27.246;r2=on;lr=on;ftag=0062B2E2-516BF931000C6A2F-2E818700;ngcplb=yes>
Route:
<sip:127.0.0.1;r2=on;lr=on;ftag=0062B2E2-516BF931000C6A2F-2E818700;ngcplb=yes>

Hope this helps.
