Several ways to skin that cat. If you prefer/need one switch, then you will probably want remote FXO in the smaller offices. Something like a Sipura SPA-3000 at the low end or moving up to some of the larger multi-fxo devices that are out there. This will put a huge importance on the quality/availability of your data circuits and provider. In Canada you have Telus in the west, Bell in central and Alliant on the coast. Allstream is smaller but nation-wide and concentrates on business. Depending on where you are (on-net/off-net) you will likely be in a wholesale market at one location or the other and this will by definition hurt your Mean Time To Repair (MTTR). Or you can have an asterisk server at each location and combine the dial plan. Depending on your calling patterns, you probably want to write some custome Least Cost Routing code (agi can work for this) to determine if it's better to trunk the call from A to B and pickup PSTN from there, or just call PSTN from your local site. You might want to have the same voice menu at each location for availability rather than have everything trunk back to one. That way, you wouldn't lose your menus if you had a network outage. You will also want to ensure the LCR code accomodates dead IP paths and automatically routes over PSTN to get there seamlessly to employees & customers. (Inbound call from site A to site B is recognized by ANI and behaves like it was an internal call trunked over IP, etc.) This way your employee sat and customer experience don't change and you just modify your phone bills dependant on how good your data providers are. dbc. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
