[Asterisk-Users] about sip and registering

As far as I understand it, that extension will be the one the external
server requests. Consider FWD example:

register = 123456:password at fwd.pulver.com/123456

Assuming your "local" extension is 2000, the context in
[fwd.pulver.com] is "fwd-incoming", when FWD contacts asterisk, it
will give 123456 as the extension:

[fwd-incoming]
123456,1,Dial(SIP/2000,45)

I think the two extensions must be the same for FWD, but for example

register = username:password at tx.voip.e164.org/3000

will call extension 3000 when an entry at e164.org is called
