412 and DTMF digits for FAX 3

Is there a way to specify how many DTMF digits should be passed from the IPO to a FAX server? Our system is programmed so that the DID fax #'s go to a hunt group. The only digits the fax server receives is the 4 digit hunt group, not the 10 digit DID.

Any ideas?
 
What do you get if the call is going directly to a Faxserver port?
 
I can call a DID fax directly, and the fax server does pickup. If I enter digits manually from the phone, the fax server will pick up on on the DTMF digits.

But when a fax machine calls the DID fax, it isnt detecting the DID fax number as defined in the IPO.

One way we tested this was by creating a user and assigning the last 4 digits of the DID, then forwarding the calls to the fax hunt group. That did work, and the fax server did pick up on the 4 digits and the fax was routed correctly.
I suppose this is a fix, but seems tedious to create 300 additional users for faxes.

I was led to believe from Avaya that the IPO would pass the 10 digit DTMF.
 
Yes this can be done. We have been doing it since v 1.4 a PRI GFI Faxmaker and a MultiTech Modem.
 
you need to route the did to a short code similar to the following

SC 666 (or what ever)
TN: <GroupNo>D.
feature DialExtn.

this will ring the group, wait for answer & then dial the DDI digits as DTMF
 
IPGuru,

Thanks for the info. Im new at this so please bear with me. I understand what you typed above, but how do I get the fax DID to use the shortcode? What should the Incoming call route be for the 10 digit fax?
 
creat the incomming call route as normal but instead of selecting a user or group from the dropdown list
manualy type the short code into the destination field
you can also send a block on numbers to the short code with 1 incomming call route entry


Incomming number = -020855566
Destination 666 <short code for fax server)

the - sign tels the IPO to match left to right so all numbers 02085556600 to 02085556699 will be passed to the sort code & the recieved DID digits sent to the fax server.
 
Arrrrghhh. Well, its working, kind of. The fax server is reading the 7594 (fax hunt group) as the DID. Heres what I have:

Incoming call route:
incoming number: DID fax
destination: *1111 (shortcode)

Shorcode:
SC: *1111
TN: 7594D
LG: 0
Feature: DialExtn

Hunt Group:
name: VHFaxServer
ext: 7594
4 extensions (the fax ports), hunting linear

When I changed the shortcode to *1111. (with the period) it did append the 1111 to the end of the 7594, so the Fax server read the DID as 75941111.

 
I've got a similar setup to Don91LX and I'm getting the same result. The IPO sends the hunt group number as the DID instead of the original incoming line number. The system is an IP412 running 2.1(27)

Has anyone overcome this problem?
 
I've always done it as follows with great results (taken from the docs, numbers given are examples obviously):

*******

In the following example, when someone dials 5551234, the system dials 501, which is then rerouted to the fax server:

Attach the fax modem to extension 216

Configure extension 216 with Caller Display Type = DTMFF

Create a Hunt Group set to extension number 500, with extension 216 as a member.

Create a User, eg. Fax501 with an extension of 501 and set Forwarding Unconditional to 500

Create an Incoming Call Route to extension 501 where the Incoming Number is the user's required personal fax number. Repeat for each user's personal fax number.

Incoming Number: 5551234

Destination: 501 Fax 501

********

Of course I would substitute the "Repeat for each users fax number" with the same idea as what IPGuru was expressing.

Incoming number: -41655512
Destination: 501 Fax 501

Thanks Peter.

I was hoping to avoid creating extra user records but that appears to be the best solution.
 
Why do you need to create extra user records? Set it up as detailed above, then at worst you might have to create extra incoming call routes, but point them all at the same destination (501 in the above example). The correct DID information will get passed through.

If you have a range of fax DID's, say 4165551200 to 4165551299 then the example I gave above would take care of them all with the single incoming call route:

Incoming number: -41655512
Destination: 501 Fax 501

You're right, I hadn't read the instructions properly. Thanks for setting me straight.
 
But I must be still doing something wrong because now the IPO sends the forwarding extension number (501 in the example) as the DTMF tones instead of the DID number. The only difference from the example above (apart from the numbers) is setting DTMFF on ext 216 didn't send any tones through but DTMFB did. I don't know if that's a locality issue or not.

I might be missing something simple here (I'm still new to the IP Office) but when it says to add the extension 216 to the hunt group, I've been creating a user with the same number and adding that to the group because I can't add the extension directly. Is that the right thing to be doing?
 
216 represents the analog port your faxmodem (or brooktrout card) is connected to. You should have both an extension entry and a user entry for this number - mind you it doesn't have to be 216, substitute whatever extension you are using.

In other words, your user "216" should already exist and you shouldn't need to be creating it.

If you want to you can send me your config and I'll take a quick look at it.

Im back. Ive been able to get DTMF to pass using a shortcode and a user set to unconditional forwarding to the fax group. Although the IPO still doesnt work like I think it should, being as we have to tell it what digits to output for DTMF. I still think you should be able to point the incoming call route for the fax DID # to the fax hunt group and be done. Thats what I understood as "...yes the IPO will pass DTMF"

Anyways, enogh of that. Has anyone had success with centralized faxing? I have multiple sites that I would like to use one fax server in one office. The fax server is only detecting the 4 digit fax group set in the unconditional forward field for the users in the remote offices. Any ideas?

 
all the advise to date "should" be working.
What version of IP firmware are you currecntly using? I suspect it may be one of the more buggy releases.
 
I have 5 406's and 1 412, all ver 2.1(27). (is that right?)
 
why do you have to create the user, and then have a user do an unconditional forward to the hunt group? why cant you just set the incoming route to forward directly to the hunt group
?
 
Because then you would get the callerID of the faxing party sent to the faxserver, instead of telling it who the fax is actually for.
