Hi, Does anyone have any real world examples of setting up Asterisk to break out to the PSTN via a Cisco router. I have a 2801 with a PVDM2-8 and -1MFT-E1 connected to a ISDN30 PRI circuit. Is it possible to get Asterisk to talk to the Cisco Router, and what is the best protocol to use. I understand the Cisco talks h232 or SIP, but am unsure as the best way to do this. If anyone has any pointers Id be grateful :) Cheers, Jo
