Hello,

No, the BYE's R-URI is ok ("Callee" side is releasing).

Probably it's the From and To header of the BYE that are incorrect.

Best regards,

Ben.

The BYE is a different transaction so the Via MUST NOT match.

Your problem is the Request URI in the BYE which is wrong:

ACK is correct:
  ACK sip:192.168.160.141:5061

BYE is totally wrong:
  BYE sip:[email protected]:6091

BYE RURI should be the same as the ACK RURI.
