Help needed in connecting ISDN BRI channel to ISDN PRI E1 channe

ujjwalkumar18894 · ‎12-19-2012

I need help with ISDN Configuration. Any help will be appreciated as i am stuck here for a long long time. I am trying to

connect an ISDN E1 PRI channel to BRI channel on different locations. I am pasting the running configuration of both the routers as well as the debug isdn q931 outputs for both the routers. Please help me with this.

Thanks in advance

Cause i = 0x82B9 - Bearer capability not presently authorized

"The user requested a bearer capability that the network provides, but the user is not authorized to use it. This might be a subscription problem. "

Data calls may not be covered by your subscription, only voice calls.

Thanks for the tip Peter. Will look into it and let you know if that was the case, I think you should be right.

Thanks again for the help, really appreciate it.

ujjwalkumar18894 · ‎12-26-2012

Peter I called up the Telco and they confirmed that the data calls are also covered. Is there anything else at fault in the above configuration? Thank you for your support, really appreciate it...
