[OpenSIPS-Users] SIP session termination doesn't work properly

Hi all,
I'm having trouble with the proper termination of SIP sessions going
through my proxy server (opensips 1.5.1)
There are 2 scenarios so far:
1) Session between two hardware audiocodec (Mayah Centauri)
The BYE from one client isn't answered by a "200 - OK" but a "404 -
Not here". First one client tries 12 times, then the other one.
screenshots from wireshark:

2) Session between two laptops using a sip-software
the BYE seems to hop from one client to the other until it times out.

Can somebody please tell if there's something wrong with the routing
logic or has a hint to what the problem might be?
I'm not so sure yet, if it's an opensips-problem, but I want to rule it
out first.
Thank you all in advance.
Best regards,
Simon
