Hi All,<br><br>This is my first email on this list so not sure what the protocol out here is. Anyways, I am trying to configure Asterisk in such a way that it would act more like a B2BUA rather than as a PBX. My customers get SIP service from their service providers and have planned on installing SIP soft phones. I was wondering whether one could configure Asterisk such that all requests coming in from the SIP phones on the LAN could be routed to an Application Server in the SP's network. Of course some intelligence would reside in the Asterisk but it would use the softswitch as its Proxy/Registrar/Feature server. In case connection to the SP goes down, then Asterisk would take over to provide basic functionality. Also using some FXS and FXO cards some kind of a fall back could be provided. Has anyone tried this out?
