asterisk users - Apr 2006 - Need help with getting EXTEN from pstn hunt group

Hi

I have a TDM card with 4 lines on a hunt group coming in.
I can answer the phones with

exten => s,1,Answer()
exten => s,n,Dial(Zap....&Zap....)
...

The problem is I don't know how to find out what extension
was originally dialed. And, trying to match on the extension
always fails. E.g.

exten => 1234567,1,Answer()  # never gets here

I thought I could get the extension on the 's' extensions above,
but, no, the extension is 's'.

Is there something special that needs to be done with pstn hunt
groups to get the extension?

Thanks

Jim,

You might want to be a little more specific:
a. You want to find out which line the call came in on, OR
b. The actual PSTN number that was dialed

An example:
- assuming a hunting pstn number 2341000
- 4 lines in a the group: 2341001, 2341002, 2341003, 2341004
- The 4 lines, are connected to your TDM card as Zap/1, Zap/2, Zap/3, Zap/4

If you want to find out which line was actually called, put each line 
into a different context in your zapata.conf, e.g.

context=pstn_2341001
channel=>1
context=pstn_2341002
channel=>2
...

In your extension.conf, you'll need something like
[psnt_2341001]
exten => s,1,Answer()
exten =>s,2,Set(DNID,2341001)
exten =>s,3,Goto(defuault,s,1)     ; Jump to normal processing

[psnt_2341002]
exten => s,1,Answer()
exten =>s,2,Set(DNID,2341002)
exten =>s,3,Goto(defuault,s,1)        ; Jump to normal processing


But, if you want to get the original hunting number 2341000, you'll need 
to use an ISDN line.

Hope this helps.

As I think about this more, and considering the solution you provide,
I think there is still a problem. Let me re-explain.

I have four numbers on a hunt group:
Zap/1-1 234-1000
Zap/2-1 567-1002
Zap/3-1 567-1003
Zap/4-1 567-1004

The published number that everyone calls is 234-1000.
I want all calls to that number to be sent to the front desk.
That means, that even if the 1000 line is busy, and the next
open line found is 567-1002, I still wan the call to go to the
front desk.

But, if someone calls 1002-1004, I want those calls to be
directed to various phones in the office.

So, it seems that it is not sufficient to know what zap channel the
call comes in on, but we need the number dialed by the caller.

Is this possible to do?

Thanks

Set up an IVR and prompt the callers to dial the extension they wish to reach.

You will not be able to determine what number was DIALED unless you have
DID service from you phone company. CF's suggestion is your best bet,
unless you move over to DID service.

The latest version of FreePBX (2.1 Beta 1 - currently in SVN, but should 
be released soon, I'm told) allows you to create inbound routes based on 
Zap Channel, which I believe is what you're look for.

You may want to grab a copy of 2.1 from SVN to see how they do the 
Zap-channel based inbound routing in extension.conf and 
extensions_additional.conf

Hope that helps,
Avi

You need an ISDN line to do that. A BRI would be sufficient if you have 
a small number of DIDs. When using ISDN, the network will send you the 
actual number that was dialed as DNIS (Dialer Number Information String) 
or what Asterisk calls DNID.
