It will do so automatically if it is working. Asterisk will stuff those
digits into ${EXTEN}, therefore you need an exten => _XXX,1,Whatever if
you are expecting 3 digits.
Until recently we had DID service from our telco on an E&M Wink
channelized voice T-1. The above is what we did.

Thanks for the reply, I'm sorry I kind of vented, I just got very frustrated
with trying to configure Asterisk for what (in a proprietary PBX) is
normally one of the easiest parts of configuration.
With a wink start T1 the DNIS digits are transmitted in-band. The Network
goes off hook, the PBX winks (goes off hook for 200ms) and then the network
sends DNIS (and ANI if used) as DTMF tones, after the PBX gets the tones it
answers the call (goes off hook). So you would tell the PBX to look for x
number of digits and then after getting that number of digits it will answer
the call. I have the Sangoma A101 configured for wink start, but I can't
find anything that says how to specify the number DNIS digits to expect. If
the PBX answers the call instead of just winking, the DTMF tones will be
transmitted during the call which is what seems to be happening here.
For more specific information a good overview of the wink start process can
be found here:

Can anyone tell me how to configure Asterisk to pickup the DNIS digits off a
wink start T1?
Thanks,

Subject: RE: [asterisk-users] Does Asterisk support DNIS?
Matt already replied to your other posting of similar content. I'm also a
bit confused. Do you mean you have observed that Asterisk is brought into
the intended context, but start to react to digits in DNIS one after
another? If so, can you estimate the interval Asterisk stays in each
extension?
If this is true, it seems to suggest that your provider is sending DNIS as a
DTMF string after Asterisk has answered the call. Isn't this a bit weird?
What does the card's manual say about DNIS (with wink start)?
