Uriel - 1) Please stop top-posting. 2) I'm afraid I don't have any data on specifics of creating a front-end. I know how to do it, but my time these days is spent writing lots of other projects that I have been doing. :-) I would suggest you get SER and set it up - it's quite easy, and

Andre: This makes a lot of sense. I had used Asterisk in the past to play the role of Gatekeeper for directing traffic to the appropriate Asterisk acting as a PSTN gateway. IAX does a heck of a good job in that configuration. However, with SIP, I have run into nothing but trouble with

I'm curently looking into using SER to front end SIP calls for Asterisk. Basicaly all SIP users would register with SER not Asterisk and then Asterisk and SER exchange registrations. SER is a very capable SIP router, much more sophisticated than Asterisk as it can look inside packets and route
