[asterisk-users] Specifying DID for outbound calls

You can check the channel-name to see which extension is making the
call and set the CallerID accordingly. The channel-name will be
something like "SIP/201-abc23ef34" or "SIP/User1-def34abc51". The 201
or User1 part depends on how you put the username in sip.conf  You can
use the CUT function to get the calling extension and then jump to the
correct CallerID. I've used something like this:

[outgoing]
exten => _1NXXNXXXXXX,1,Set(Outgoing=${CUT(CHANNEL,/,2)})
exten => _1NXXNXXXXXX,n,Set(Outgoing=${CUT(Outgoing,-,1)})
exten => _1NXXNXXXXXX,n,GotoIf($["${Outgoing}" = "User2"]?20:10)
exten => _1NXXNXXXXXX,10,Set(CALLERID(num)=3012323434)
exten => _1NXXNXXXXXX,n,Set(CALLERID(name)="User1")
exten => _1NXXNXXXXXX,n,Dial(SIP/${EXTEN}@vitel-outbound)
exten => _1NXXNXXXXXX,n,Goto(h,1)
exten => _1NXXNXXXXXX,20,Set(CALLERID(num)=3013232322)
exten => _1NXXNXXXXXX,n,Set(CALLERID(name)="User2")
exten => _1NXXNXXXXXX,n,Dial(SIP/${EXTEN}@vitel-outbound)
exten => _1NXXNXXXXXX,n,Goto(h,1)

But in my case I had two different domains. E.g.
Dial(SIP/${EXTEN}@provider-ID1) and Dial(SIP/${EXTEN}@provider-ID2)
instead of setting the CallerID.

Not that the Cut doesn't work correctly if you use a minus-sign in the username.
