Hi Bogdan,
Thanks again for your response.
I understand your point but as fair as I know if the contact is set to
50257609195 at 192.168.2.165:5061 the subsequent messages (i.e. ACK and BYE)
will be sent directly to the callee bypassing the proxy. This is OK for me,
but I understand that the LB needs to receive the BYE message to keep track
of the available resources.
Please correct me if I'm wrong.
Thanks
Diego

Hi Diego,
The bug seams to be in your callee device. Take a look at the 200 OK it
sends:
U 192.168.2.165:5061 -> 192.168.2.165:5060
SIP/2.0 200 OK..From: "Your Long
Name"<sip:Username at 192.168.2.150:5060>;tag=A46E9878A6B36612423768382DD6C758.

The 200 OK is sent from 192.168.2.165:5061, but in contact it places
sip:50257609195 at 192.168.2.165 -> the port is missing, so the sequential
requests are going to the wrong destination (to
sip:50257609195 at 192.168.2.165 which is actually the LB ,not the callee)

Bogdan
