The PRI will allow you to publish/distribute a virtually unlimited number of PSTN telephone numbers (DID's). The Telco will send calls destined to your DID's over your PRI to be processed by your Asterisk Server. The PRI will allow a maximum of 23 simultaneous conversations, whether they are inbound or outbound (your PRI can be provisioned by your Telco for inbound only, outbound only, or both inbound and outbound). If I understand your scenario correctly, once the calls come in vis the PRI, they will transferred/routed to a destination via VoIP, using an Internet and/or some network connection. In this scenario, the PRI will only be needed for inbound calls.
Hope this helps.

Im thinking of deploying a call routing service through asterisk. Basically I want people to be able to call a number through the PSTN and then call whatever extension to be routed through a voip termination provider. Im guessing using a PRI is the best way to do this. However, im confused as to how it all works. Say a PRI has 23 usable channels, does that mean that I will be able to route 23 calls at the same time or does it mean that I would have to split 11 channels for incoming voice traffic(from PSTN) and 11 channels for outgoing voip traffic? Im stomped =\ _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
