Your phone would have to support registering with more than one sip server. It may seem like what you want, but I doubt it is necessary. > 2) Why we need a section in the sip.conf for the > proxy, say, Free World Dialup's fwd.pulver.com?

You should be able to register and listen for calls from multiple fwd numbers and direct them to different extensions. > 3) Can anyone explain the meaning of "peer", "friend", > "user" in more details?

Friend: an attempt at a combination of both, to simplify set up of phones that send and receive calls.

Hmm, let me give brief examples of things you can do(* = asterisk): sip phone -> * -> sip phone sip phone -> * -> hardline adapter -> PSTN or T1/E1/BRI/etc. sip phone -> * -> other voip service(fwd, iaxtel, etc) sip phone -> * -> other voip service(voicepulse, nufone, iconnecthere) -> PSTN Most(if not all) of these can be turned around so that they are still valid reading right to left. ----- Andrew Thompson http://aktzero.com/ http://www.retirequickly.com/43653 _______________________________________________ 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
