Andrew, Thanks for help. But you still doesnot answer my questions. Please see the inline comments.
BTW, I use "Getting Started with Asterisk" as reference (http://www.automated.it/guidetoasterisk.htm#_Toc49248767).

In my case, each SIP phones register with FWD, and was assigned a extension. I can put more register for each phone in sip.conf. For example, register => 21103:[EMAIL PROTECTED]/1000 register => 21104:[EMAIL PROTECTED]/2000 My concern is how to setup the [fwd.pulver.com] [fwd.pulver.com] type=friend secret=mypassword username=my fwd number host=fwd.pulver.com since there are two FWD numbers, should I set secret and username for each SIP Phones? Also, you still doesnot answer my question, what is the use of section [fwd.pulver.com]? Why we need secret and username in [fwd.pulver.com] since we already provide it in "register => 21104:[EMAIL PROTECTED]/2000"? > > 2) Why we need a section in the sip.conf for the > > proxy, say, Free World Dialup's fwd.pulver.com?
