asterisk users - Oct 2005 - Incomming call line identification (NOT CallerID)

Hi,

  Ok, here is the setup. Asterisk conected to a PRI line (23 lines). 3 
tool-free phone numbers are routed to this PRI line.

  Customer wants to have a way to have shown on the receptionist phone 
that the call comes from which of the 3 tool-free lines. Possibly 
display on the phone that the call comed from tool-free number 1, 2 ou 3 
or even better a name or text id associated with this tool-free nmber.

  This is not callerID but rather identify what tool-free number the 
caller dialed in order to reach the PBX through the PRI line.

  Any helps or hints appreciated.

The SetCallerID command springs to mind. However, how do you know when 
you are getting a toll free call? Does it come in to a certain extension 
number on the PRI or is it just sent to the PRI's lead number?

If your CLEC sends you the call to a specific number and each of the 3 
lines have a unique call-to number then the SetCallerID would work. You 
would however loose the original callerID if that is important.

Frankly in a business environment I can see no use for callerID. What 
are you going to do now that you know I'm calling; ignore my call? As a 
business you would pick up the phone regardless of whome was calling. 
Indeed, I can see instances where you would want to prevent it from 
being displayed (helpdesks for example) to stop folks from ignoring calls.

This is DNID, and should already be present in the appropriate channel 
variable when the call arrives in Asterisk.
