[Asterisk-Users] sip peer dinamically

[Martin Morey]

I want to let users defined on sip.conf to dial on differents accounts to 
an external sip proxy, the account id will be the same for the users and 
the external sip proxy so I can use as known variable

Each user is registred to my *-box with [externalsip] context

On the extension.conf, how should i define the Dial/SIP command?

[externalsip]
exten => _.,1,Dial(SIP/${EXTEN}@${CALLERIDNUM}:sipserveripaddress)
or something like this
