Routing faxes to DID's? 1

[usmc4life]

I have a customer that has a block of of DID #s for extensions and they want to be able to route faxes using the same DNIS that will point to their Exchange / UM mailbox. They don't want to purchase additonal DID for the faxes.

This customer has an S8500 with CM 2.2.

Could this be done with Vectoring? If, so how difficult would it be to do.

Thanks!

I would do it with UDP and AAR. Place the range of numbers into the UDP tables and front end it with some aar code and translate it to whatever TG/path you need.

Dunstan,

Can I do UDP and AAR without vectoring or will I need to purchase vectoring?

 

[Dunstan]

Depending upon your release these are independant options. I believe you would get aar and UDP as a part of any multi-vantage release or later in other words at 2.2 these functions should be in place.


No vectoring is needed and it is probably the preferred method for routing blocks of numbers to adjunct equipment such as fax servers UM devices other pbx's etc.

We have two fax servers here that I push a couple of hundred did's to and the total entries it takes to accomplish this via udp is minimal.

Dunstan,

Could you possibly give me an example of what entries are required in the UDP table? My knowledge in UDP is very minimal.

Thanks again for your help!

Here is the UDP table entry for the 58xx did range (First entry top left)

58 is the first 2 digits of a 100 block range I send to the fax server. the 444 is a set of digits for routing purposes in the AAR table...I will post the corresponding routing table and aar entry below. UDP gets the range adds some digits and sends it to the AAR table for routing.

aar analysis 444 Page 1 of 2
AAR DIGIT ANALYSIS TABLE
Percent Full: 4

String Min Max Pattern Type Num Reqd
444 7 7 444 aar n

This is the aar table where the 444+whatever was sent to the pbx from the pstn example...444+5800.



Below is the route pattern that AAR directed the call to take

2: 7 0 3 n user


Trunk Group 2 and TG 7 are PRI's that feed directly into our Fax Server. Here in the RP we strip back off the 444 and push down the original 4 digit did that was passed to us from the C.O. ex 444+5800 now becomes 5800 again and those digits are passed to the fax server.

Hope this makes sense

I should say the above example is for calls that come to us from the PSTN. We recieve 4 digits from the lec that is why I am using 58xx as the example. From the outside world that call might look like 678-555-5800 but the lec will send us only 5800 on a call like that.

Dunstan,

I will let you know how it works. I will be implementing this with an upgrade in the middle of December.

Thanks again!!!
