Hey guys, i just got an sip trunk, and i figured out how to register and make an extension that dials that trunk, but i don’t know how to pass a number to it.

What i would like to do is have it so that when a user dials “9”, they can then enter the number to call, and it will pass through the trunk.

Also, i have it so that Google Voice (NOT my trunk, just a toy to learn with) dials [000@my.ip.address](mailto:000@my.ip.address) (they can’t use domain names yet) my server gives an “extension not found” error…

Any ideas? Thanks.

Ok, nevermind. To get outbound calls by simply dialing out, you just use:

exten =\> \_NXXNXXXXXX,1,Dial(SIP/out-residential/1${EXTEN})  
exten =\> \_NXXXXXX,1,Dial(SIP/out-residential/1513${EXTEN})

or to differentiate outbound routes (in case you have 2 numbers):

exten =\> \_9NXXNXXXXXX,1,Dial(SIP/out-business/1${EXTEN:1})  
exten =\> \_9NXXXXXX,1,Dial(SIP/out-business/1513${EXTEN:1})

and the reason why inbound calls to 000 was not working is because i did not have my TRUNK’s sip user configured to use the same context as the user 000.
