Hi Hamid,
If you use PATH support on the proxy, this should translate into UAS
adding an extra Route header when routing calls back the UAS.
Nevertheless, the PATH does not interfere and change anything when comes
to the sequential requests.
Could you post the 200 OK between UAS-proxy and proxy-UAC ?

Bogdan,
I am using path module on Both servers (Proxy - add_path_receive() and
UAS - use_received 1 ). UAS change the Contact header of 200 OK with
the IP given in field 'path' in table 'location'. But when I make a
call by bypassing proxy, UAS did not change the contact header. What
am I doing wrong in using module Path ?

Hi Hamid,
There is something wrong with the contact in the 200 OK - as you see,
the 200 OK reply from proxy to Alice contains in the Contact header
the IP of the the proxy, while it should contain the IP address of BOB
(the issuer of that reply).
Because of that bogus Contact header, the whole in-dialog routing (for
the ACK) gets broken.

ACK must be sent to TOP most Record-route first but its going to
sceond Record-route first. Is it a correct behavior ?

I beleive you have to engage NAT corrections in reply route for
200OK.
I havent seen your SIP trace but if im Comtaact header the IP is
of UAS and it goes to the caller side ACK will get directly to
that IP.
Just my guess. Need more info from you.

Sammy
