I have a cisco 3825 with 2 interface 4 ports cards BRI ISDN, actually I'm doing calls to the PSTN by voip with a SIP proxy.
But now I want to do and receive the calls via ISDN ports. From and to the PSTN
The cards has been recognized perfectly.
I have problems for configure it, Could you indicate me the form for configuring
Do I need the dialing plans? Dou you have any example?
Thanks a lot
