Specific Outbound Trunk per Extension

Asterisk Asterisk Support
1

I am trying to phase asterisk, to prove its greatness, into an exisiting phone system. The only hang up (no pun intended) is that when a user dials an outside line, I need to be able to specify which Zap channel to use (that way extension 411 looks like extension 411 on the older phone systems caller IDs).

I was thinking that I could use some combination of GotoIf and MACRO_EXTEN to make this magic happen. Right now I’m only concerend with two extensions and zap channels. I would like, when a person dials from “SIP/411” that they get Zap/2 and when they dial from “SIP/299” the get Zap/3 for the _9NXXXXXXX or _91NXXNXXXXXX extensions. I just can’t figure it out though - I’m fairly new to this and would really like to make Asterisk shine - everything else works great.

You could use some goto ifs based on the callerid or you could have seperate contexts and specify individual contexts for 411 and 299, example below:

[411]
secret=411
type=friend
context=411

[299]
secret=299
type=friend
context=299

Would this work - I posted my extensions.conf, zapata.conf, sip.conf? See any problems?
