Newbie Question re DISA MICS 4.0 and NAM - PBX Info :: Your Free PBX, PABX and Telephone Information Resource

07-13-2004, 07:53 PM

I found this forum using a web search, and man is it ever helpful!

We recently moved to a PRI and have DISA working on a DID number. The Telco provides seven digit information on thePRI, so when I dial an internal number (after providing a COS password), I have to dial all seven digits to get to a local number.

Is there any way to get DID working on a 3 digit extension from our main telephone number? We could then use our toll free number (pointed to our main auto attendant line) for remote access and gain an outside line with a COS password (after dialing the 3 digit extension).

Any advise you can pass on would be greatly appreciated.

Regards,

pbrac.

I guess I'm just nor understading what you're trying to accomplish, but as a general rule of thumb, I try to match my extension number length to the received length. Your service provider should be able to reduce your DNIS to 4 digits in stead of 7. As far as DISA, once you get past the COS password you should be able to dial any internal extension. You have to set up a remote package to be able to dial out. Hope I've helped a little.

Maybe this will help...
1) Define the DISA DN to match the trailing digits of the
Called Party Number (CDN).
With Public, Private, and Tie service types, the CDN is
simply truncated to the Target Line Receive Digit Length
and is parsed to match the Target Line Receive Digits.
DISA can be accessed by having the DISA DN match the
trailing digits of the CDN. For example, with a Receive
Digit Length = 4, and DISA DN = 1234, a call made to
Public DN 763-1234 will be handled as follows:
• the ISDN setup message will contain a CDN of 763-1234
• the CDN will be truncated to the four digits, 1234
• 1234 matches the DISA DN
• the call will be answered with DISA

Thanks for the reply.

We have two very different sets of DIDs (4xx-9xxx and 7xx-9xxx), so we apparently have to have all seven digits passed to our PBX.

What I wanted to do was to be able to dial into our toll free number on our main line when we are travelling to utilize DISA to make outgoing long distance calls. This is way way cheaper than using calling cards. I did not want to get another toll free number that users have to remember to use DISA (see below).

I called two companies for technical support to see if you could use remote access from the automated attendant (ie dial a 3 digit local) after calling the main number. Apparently you have to use DISA or Auto DN to use the remote access features. I don't know how to use Auto DN, and DISA apparently has to be on a specific trunk.

What I perceive to be the best solution is to get another toll free number and point it to the DISA line so that people who are travelling can use it.

Unless you or someone else has a suggestion as to how to implement this without using a DID number, we will all have to remember another toll free number I guess.

Thanks in advance for any further help you can provide.

How does your 8YY number ring in? On the PRI or a regular trunk?

I'm not sure how to answer that, I guess. All of our lines are on the PRI. Our main number is answered by the automated attendant. All other numbers were converted to the equivalent of DIDs (including our fax machines on ATAs).

It rings in on the main number.

Well, from what I gather, your 8YY number is pointed at the same rec'd digits (DNIS) as your main local number. In that case I would order another 8YY number to be pointed at an unused DNIS and program your DISA DN to match the last 3 or 4 digits (depending on you DN length). When you call that number you should receive the studder dial tone requesting the COS password. After a COS password is entered, depending on what remote access package you assign to that COS PWD you can dial any internal extension and or destination code (9 and then the number) to get out. Does this help?
