Unanswered Question

I have a couple Cisco ISR 2801 routers running c2801-spservicesk9-mz.124-9.T3.bin IOS.


I am getting the follwing error on my ISDN calls across the (Verizon) PRI:


Cause i = 0x82E3 - Information element not implemented


I have the following configuration on my


Call Manager for the PRI:

Calling Party Presentation: Default

Calling Party Selection: Originator

Called party IE number type: unknown

Calling party IE number type: National

Called Numbering Plan: Unknown

Calling Numbering Plan: ISDN


Any suggestions on what the problem is?

82 stands for "Identified Channel Does Not Exist". This could be a telco problem with their provisioning. Can you also paste your configs on the controller and serial interface (s0/0:23 or smilar) ?

Possibly the switch doesn't like the name IE.

On the router please do "term mon" and "debug isdn q931" to see the complete call progress.
