[asterisk-users] ISDN PRI Caller ID problem

[A.R. Nasir Qureshi]

Dear Matthew,

Thank you for your reply.

Please tell me if there is any way I can see the actual q931 message received from the card without any translation / filtration / alteration by the software or the driver ?

How much the switch type or other configuration variables affect the SETUP message being received ? What I am concerned is that may be the wrong switch type or other parameter may be causing the problem.

This is my first attempt at configuring an ISDN, and I want to be sure before I go after the telco.

Regards,


Nasir.

Tell them they are wrong.  There is no calling party number IE in that 
SETUP message below.  :-)
