[cisco-voip] how to map DIDs to extensions during SRST

Thanks Robert, I think this is might be what I'm looking for. 

Only thing is, it seems that I can only have one "translation-profile incoming" on the voice port, and only one "translate called" ont he translation profile. This means, with the max of 15 rules per translation rule, I can only have 15 DIDs (assuming no extension matching).

Is that right? There has to be a way to scale this a bit more. No?

  If I understand the question, we use translation patterns on the inbound 
  dial-peers

  voice translation-rule 33
    rule 1 /^16/ /3316/
    rule 2 /^7111/ /331600/

  So, an incoming number that starts with 16 gets converted to 3316
  A number that starts with 7111 gets converted to 331600 (our receptionist)

  voice translation-profile PREFIXDID
    translate called 33

  voice-port 0/1/0:23
    translation-profile incoming PREFIXDID
    input gain -3
    output attenuation -6
    echo-cancel coverage 24
    echo-cancel erl worst-case 0
    playout-delay minimum low
    no comfort-noise

  As far as assigning extensions, when the phones go into SRST mode, 
  _they_ tell the router what their extension is, so that's built 
  automatically.  So if you had a 6-digit extension on line 1 that will 
  automatically get configured on the router.
