asterisk users - Mar 2008 - Unable to obtain dialed number through ZAP

Hi all,

This is not a repeated post as I am just adding more information for my
previous post.
Asterisk version 1.4.18
TDM card: Digium TDM411B
Zaptel version 1.4.9.2
Line: PSTN line
I tried to obtain the dialed number using $DNID and $CDR(DST) .  All of
these variable returns 's'
I also tried exten => _3345335,n,Noop(this is ok)  where 3345335 is my
number but it does not go there.

What I need to do is to try to route called based on the dialed number as I
have multiple DIDs on my line.  Is this something that can be done?  Is this
something to do with the hardware that I am using?  If so, what kind of
hardware do I need to accomplish this task?

zapata.conf:

[trunkgroups]

[channels]
usecallerid=yes
hidecallerid=no
callwaiting=no
threewaycalling=yes
transfer=yes
echocancel=yes
echotraining=yes
immediate=no
; define channels

context=incoming
signalling=fxs_ks
channel => 1

signalling=fxo_ks
channel=>2


Thanks,
Mark

Based on this and your other posts, I'd suggest that it's not possible 
with your setup. Telephnoe companies don't normally send the called phnoe 
number down analogue lines, just the calling number (and even if they did, 
I'm not sure asterisk has a means to extract it)

To do what you need to do, you'll need to move to BRI or PRI type of 
equipment. (ISDN2 or ISDN30 in the UK, or whatever they're called where 
you live)

As others have mentioned, if you have an analogue connection (and even in some 
cases, a digital one), this information is not available to you.  A properly 
configured PRI or BRI should get you this data, and if you have a 
specifically-provisioned CAS T1, you can get it.

-A.

Hi Mark,

It looks like you're using an analog line so you don't have the 
advantage of a dial line telling you the dialed number.

If your provider has enabled distinctive ringing on your line you might 
be able to accomplish this.  I have never tried to have asterisk 
recognize distinctive rings and this wiki page doesn't look too 
promising, but take a look:
