SIP connection issue

[Karik]

Hello.

Could you help me with the issue of SIP connection between phones
Panasonic tried to connect to each other via Alcatel OMNIPCX?
Connection is almost ok, but last ACK answer doesn't translate
to the second phone through Alcatel proxy server. I don't know why.
Could you advise me what should I check?

Maybe play with SDP parameters in Alcatel SIP gateway (do not forget to restart sipmotor).
