Can this be done?

[gshaheen]

I have a customer who has a CLEC that wants to install 2 PRIs with DIDs into their 2 Magix systems. The 2 systems are located a few miles from each other, so each would have its own PRI.

I have done this many times, so not a problem, except..........
The carrier is trying to sell the customer on being able to "4-digit" dial(almost like Centrex)from one site to anoher using the 2 PRIs with a "dial plan" they create in their CO

The carrier is telling me that if I send them 4 digits only, they will map it to the DNIS digits of the PRI at the other Magix site and allow my customer to dial from desktop to desktop using this method.

I think technically they can do it, but I am concerned about the ARS tables in the Magix. Can I program entries of only 4 digits and still have the call go out on the PRI?

Or should I bypass ARS and have my dial 9 access code go direct to the trunk group of the PRI?

Thanks.

Hmmmm....

Very Interesting...........

HOWEVER, I think there may be a couple of ways we can make this work.

The Ideal Solution would be the End Users could dial just 4 digits to call each other.

Let's put that aside for now.

Another way would be they dial a "SPECIAL CODE" (like 5) to access the POOL that lets them dial only the 4 digits to the other switch. (This May or May Not work...it's just a "design thought" at this point, considering the Vendor will be doing this over the regular OUTDIAL Lines.)

-OR- They could dial a "SPECIAL AREA CODE" that would route them to the ARS TABLE that then ABSORBS THE AREA CODE and sends then on their way. (This would work for sure)

Now, back to the 4 digit idea.....

You MAY (or may not) be able to set up a UDP Table that can route the 4 DIGIT calls to the other switch.

I say that because, USUALLY, such routing is done over DIFFRENT POOLS, that is, other than the "REGULAR" pools for outgoing calls.

If anyone has ever done this, PLEASE POST.

Again, I really think it can work, but I have never had the oppertunity to try such a thing.

MM,Gshaheen,
This is what is referred to as "on-net" dialing. You can have a 2-4 digit facility (location) code depending on the complexity of the network (number of nodes)that identifies each node to the carrier. The code must be output to the carrier to be used for routing on their side. The principle is the same as a networked big switch (Definity:et al)using dedicated tie circuits except it is on the carrier level using their network. The best use is a 3-digit facility code and 4-digit dialplan (good ole 7-digit dialing) You could probably use UDP since the circuits are already networked and you are only receiving a 4-digit DNIS anyway. It would be an interesting exercise on the Magix doing multi-node, but only 2 nodes would not be too bad, a single voice mail could be a bit tricky, easier with 2 seperate VM's, I would think.
