[Asterisk-Users] How does asterisk know the did called on?
If I were to buy 20 did's how do I know within asterisk which number was
dialed? (like say I want a few of the did's to ring specific extensions
if they are dialed and others to go through the menu)
Is there any ${var} that has the number dialed in on? (that would be
optimum).
-Courtney.

Courtney,<br>
<br>
This really depends on the type of channel you are using. We use CAPI
with one of our customers and they have ten DID's (DDI's in NZ) and use
four BRI lines. Here is a snippet from their extensions.conf that
shows how it dials certain extensions based on the number dialled. The
three digit number in the dialling rules are presented by the ISDN
channel/CAPI and will probably be slightly different based on your
telephony provider. We had to dial one of the DDI's and see
Asterisk
reported it as being on the console to figure out how long the DDI
number was.<br>
<br>
(Note that you would be much better off using macros rather than the
numerous entries that we have in extensions.conf, but we have
structured it like this upon customer request).<br>
<br>
;[incoming]<br>
exten => s,1,Answer<br>
exten => s,2,Dial(SIP/9295,20,t,)<br>
; No answer or busy, so dial other extension(s) - can add others to
this list if required<br>
exten => s,3,Dial(SIP/9295&SIP/9287,,t,)
<br>
;Queue not set up, do not use the following unless configuring it
first.<br>
;exten => s,3,Queue(receptionqueue)<br>
;DDI's follow<br>
;Manager (290)<br>
exten => 290,1,Answer<br>
exten => 290,2,Dial(SIP/9290,,t,)<br>
exten => 290,3,Voicemail(9290)<br>
exten => 290,4,Congestion<br>
;Supervisor 1 (291)<br>
exten => 291,1,Answer<br>
exten => 291,2,Dial(SIP/9291,,t,)<br>
exten => 291,3,Voicemail(9291)<br>
exten => 291,4,Congestion<br>
<br>
Hope this helps.<br>

(that would be > optimum).It varies as to how each provider handles this, but the majority of those I've tested with send the DID number as the extension dialed. As an example, when livevoip sends an incoming 800 call (did is the same) to my * box, they send the call to extn 8001234567 and I handle it in the extensions.conf like this: [livevoip800] exten=>8001234567,1,Dial(SIP/3000,10) A customer uses a PRI with about 30 did's. Each incoming DID call includes the dialed number, and the above approach is used to map those incoming calls to specific extensions. A variation of the above is to use a GoTo statement (instead of the Dial statement) to send the call to an existing context/registration.

(that would be > optimum).Your provider will "outpulse" a certain number of the DID digits for you. You may have a choice as to how many digits you want outpulsed. You can then use these outpulsed digits just as an extension. E.G. if you have (555) 555-2000 through (555) 555-2019, and you have four outpulsed digits, you could make them go to your various extensions/contexts like this: exten => 2000,1,Goto(IVRMenu,s,1) exten => 2001,1,Goto(SIPExtensions,101,1) - Noah

(that would be > optimum).Your carrier can tell you how many digits they will send to you. Asterisk sees these digits and will match exten => 1234,1,Blah if the carrier sends you 4 digits. Remember Asterisk does not really support DID on analog ports, only T-1/E-1 (including PRI) ports , BRI ports, and VoIP ports.
