[asterisk-users] pattern regexten and dialing to trunk

[Neko]

Hi list! I'm currently stucked and don't know how to properly resolve 
next situation:

I'm using asterisk with regcontext and regexten, so far its works: NoOps 
with prio 1 dynammicaly added or removed as expected.

Example: 3 trunks: tr1 with regexten _1XXX; tr2 with regexten _2XXX and 
tr3 with regexten _3XXX

   '_1XXX' =>        1. NoOp(tr1)                                  [SIP]
   '_1XXX' =>        2. Dial(SIP/tr1/${EXTEN})                     
[pbx_config]
   '_2XXX' =>        1. NoOp(tr2)                                  [SIP]
   '_2XXX' =>        2. Dial(SIP/tr2/${EXTEN})                     
[pbx_config]
   '_3XXX' =>        1. NoOp(tr3)                                  [SIP]
   '_3XXX' =>        2. Dial(SIP/tr3/${EXTEN})                     
[pbx_config]

I can't just write _X.,2,Dial(SIP/${EXTEN}) because it is trunks, and i 
have to write extension with priority 2 for each trunk i have.

It is possible somehow use _X.,2,Dial(..) in this situation? because 
when it is just 3 trunks it is not a big problem, but when their amount 
is about hundred...

....


I'm thinking about adding additional option "regapp" to set custom app 
instead of default NoOp. Something like this:

sip.config:

[general]
regcontext = internal
regapp = Set(CALLED_TRUNK={$name})

[tr1]
...
regexten = _1XXX
...

dialplan show internal:

[ Context 'internal' created by 'pbx_config' ]
   '_1XXX' =>        1. Set(CALLED_TRUNK=tr1)                      [SIP]
   '_2XXX' =>        1. Set(CALLED_TRUNK=tr2)                      [SIP]
   '_3XXX' =>        1. Set(CALLED_TRUNK=tr3)                      [SIP]
   '_X.'   =>        2. Dial(SIP/${CALLED_TRUNK}/${EXTEN})         
[pbx_config]

But i hope it is possible to achieve this with default options...
