[OpenSIPS-Users] Processing calling-name(CNAM) from PRI

[Zahid Mehmood]

Hi,
   I am having trouble figuring out how to process the calling-name coming
from the PRI. In my setup, PRI is connected to a Cisco media gateway which
sends traffic to the proxy servers.  Calling name is not coming  in the
ISDN setup message.  It is actually provided in a separate facility message
[1].

Cisco gateway processes this secondary messages and generates a INFO
message.  Polycom phone sends the 200 ok message but there is no change in
the visible caller id.

Does anyone have a working example or suggestion of how this is supposed to
work?
