I'll answer this since I just had mine installed and went through this. Signalling comes in just a few options at the base level and is specific to the T1 transport. Your options are ESF or D4 for framing, and AMI or B8ZS for error detection. Your PRI rides on top of the T1 transport. In the PRI your DIDs are passed as part of the call setup in Q.931 packets on the D channel. Specifically you will place all your incoming PRI lines into a context in extentions.conf and then you will make extensions with the incoming phone numbers or part there of if your telco provider isn't sending the whole called number. In these extension deffinitions you can redirect the calls to either the appropriate IVR menu, or an internal extention. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
