[SIPForum-discussion] One way talk path

[Chaurasia, Punita (Punita)]

Hi all,
 
I am new to SIP world. I would like to know what exactly to look for
'one way talk path' issues with sip calls.
 
we have a avaya communication manager -- ses -- alcatel sip
configuration. If a  Digital station (DCP) calls an sip end point on
Alcatel switch .. the call works fine .. but with the reverse.. there is
no talk path.
 
I have the sip call logs for both the calls .. but not able to
understand ..what exactly should I look for ..  in order to find out the
issue.
 
Need your expert help.
 
Thanks!
 
Punita
