 Posted: Mon Mar 24, 2008 1:38 am Post subject: [asterisk-users] 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.

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:

Just chiming in here...
There was discussion a LONG time ago about a setup similar to this. I
can't remember the details, since this was something I didn't expect
to ever run into myself (I guess I'm self-centered on that one).
Anyway, the discussion was along the lines of setting the line up as a
analog T1. I don't know if the card being used was for a T1 as well
or if it was a regular analog card.
You might try searching Google and see if it can bring up that old
conversation. Honestly, I can't even remember if the person ever got
it to work correctly or not. |

You're talking about DNIS: Dialled Number Identification Service.
Some telcos can provide it on some analog services, usually those
described as DID, terminated on Dialogic DID-120 cards, and sold to
answering services run by little old ladies with 4-digit nixie tube
display boxes on the shelf next to the WeCO 300 (and no, to coin a
phrase, I am *not* making this up).
IOW: Yeah, go get ISDN.
Cheers,

DID = Direct Inward Dialing
In the telephone world, DID has been available for many years.
Originally as a specialized trunk or set of trunks, where the PBX or
remote end supplied battery towards the CO, and the CO outplused the
last number of digits to the PBX, depending on the size of the PBX this
could have been 3 or more digits. Later DTMF. What you would call an
analog connection.
With proper coding Asterisk SHOULD be able to handle DID trunks with FXS
circuits.
Asterisk can PROVIDE DID access to a PBX via FXO circuits, assuming the
PBX can be programmed for no wink.
Answering services did use devices to decode and display the digits (
Nixie or LED ) so they would know how to answer the line, often on a 1A2
key set. This has evolved in later years to more automated systems.
Somewhere along the line, DID has become misused. What many call DID is
LDN, or Listed Directory Number. LDN is usually the Line Number, though
not all lines have numbers. Many telcos provide a group of lines or
trunks under one number with multiple appearances in a hunt group, often
tarriffed at a different rate.
Probably more than anyone wanted to know about Direct Inward Dialing
