[Asterisk-Users] SIP URI matching

[Geert Nijpels]

Hi,

Can somebody tell me how to do SIP uri matching?

I have in my [from-sip] context a few extensions included, this works. 
So I can call:
312 at xxxx.net

But I also want to be able to call my sip [peer] or user name. Is this 
possible? As in:
geert at xxxx.net

Also, what do you guys do for outbound sip calls? Currently I have a 
prefix for it:
exten => _9.,1,Dial(SIP/${EXTEN:1}@${SIPDOMAIN})

Kind regards,

Geert
