[asterisk-users] DAHDI FXO calls and the 's' extension. No, Jackie-O doesn't work here--it's just an example. Sheesh!

[Karl Fife]

Calls that come in on DAHDI FXO ports are routed to [context], extension 's'

INSTEAD, I would like to route specific ports to specific extensions, For 
example:

I want DAHDI/1-1 to go to 1234
I want DAHDI/1-2 to go to 2345
I want DAHDI/1-3 to go to 3456 ...etc

What is the CLEANEST way to do this?

Yes, I can create a private context for each DAHDI channel but that seems 
messy and verbose.
[useless-context1]
exten => s,1,goto(context,1234,1)
[useless-context2]
exten => s,1,goto(context,2345,1)
[useless-context3]
...etc

Slightly better, I can eliminate other contexts by hooking the channel 
variable, like this, but this also messier than it COULD be.
[context]
exten => s,1,GotoIf($["${CHANNEL}" = "DAHDI/1-1"]?1234)
exten => s,n,GotoIf($["${CHANNEL}" = "DAHDI/2-1"]?2345)
exten => s,n,GotoIf($["${CHANNEL}" = "DAHDI/3-1"]?3456)...etc
exten => 1234,1,Dial(${BIGFOOT})
exten => 2345,1,Dial(${LOCHNESS-MONSTER})
exten => 3456,1,Dial(${JACKIE-ONASSIS})...etc

Is there a way that I can simply specify the extension associated with a 
given dahdi channel in dahdi_channels.conf? It would seem logical, but I'm 
finding no love.  If you also know for sure that there ISN'T a way to do 
what I'm asking, I'd like to know that too.

Is there a way to state something like:
context=2345 at privileged-out
or
context=privileged-out
targetexten=2345

in dahdi-channels.conf ?

Please advise.

Thanks!

p.s.
Bigfoot DOES work here.
