BTW. This seems kinda backwards. Why not just get a PRI. PRIs have all the intelligence you need to do it right.<br><br><div><span class="gmail_quote">On 2/18/07, <b class="gmail_sendername">Matt</b> <<a href="mailto:mhoppes@gmail.com">

<br>but DNIS and ANI can be variable length without confusion if the sender<br>uses the "*" DTMF tone as a delimiter. Thus sending *ANI*DNIS* (pronounced<br>"Star ANI Star DNIS Star" allows the receiver to identify the two values
<br>unambiguously and to find the trailing boundary (when the 3rd "*" has been<br>received).<br><br>We have a Channelized Voice T1 from a long distance provider that is set<br>up this way into our non-Asterisk PBX where the provider sends us ANI as
<br>the full originating phone number and DNIS as the "last 4 digits". So the<br>DTMF string seen by our PBX for someone calling one of our toll-free<br>numbers, say 800-123-4567, from a local phone in Hawaii, say 808-555-1313,
<br>would be "*8085551313*4567*". The PBX parses this string and uses the<br>last 4 digits DNIS to route the call from the T1 trunk group to the proper<br>internal extension or hunt group.<br><br>Do Asterisk and Digium or Sangoma T1/E1 cards know about delimited ANI and
