I am having the problem in setting up ISDN BRI connection to PSTN. I am runnign Cisco CME 4.1 on Cisco 2801 router platform. I am having simply two Cisco IP phoones. They are registered to CME and I can make the calls between them.
I am trying to make PSTN connection, but without the sucess. I cannot make outside calls and inside calls are not also pssible. In the attachmet there is debug isdn q931 commant.
If some one can help. thanks in advance
Understand, TEI is classic case of problems with BRI.
Now, I think that if you get to know username and password that are configured on the Patton, you could eliminate it completely, terminating the SIP trunk directly on the router. An easy way to do that, is to place an ethereral on Patton's ethernet.
To make more ephone ring simultaneously, create an ephone-dn with the called number, then assign this ephone-dn to multiple ephones via button command.
Hope this helps, please rate post if it does!
