[Asterisk-Users] Another PRI based question
In speaking to the representative at Verizon, we came to the conclusion that DID numbers were not the correct solution; however we were told by Verizon that they could do something called assign individual numbers to the PRI. What this would in effect do is give us an additional phone number that we would like to route to a specific extension; however unlike the DID number, it would not be assigned to a specific channel. It would hunt for an available channel. What we would like to be able to do is that even though it doesn't come in on a specific channel, still be able to route it directly to a specific extension. The representative at Verizon said that we should be able to do this by having the PBX recognize the digits that come in on the line and route it to the specific extension accordingly. Is there a way to do this in asterisk? Thanks again. AJ

You want the DIDs to be delivered as the full length number, 10 digits. This lets you put all your incoming calls into a simple context where you define extensions that direct the incoming phone number to a specific function or internal extension. While them delivering 10 digits may be overkill for DID, it allows you to get DID numbers from different exchanges without any problems. Also you may want to make sure they let you set your callerid number on outbound calls. It is helpfull for my setup since my office phones present the main number for the office. The last DID we have is what I use for my home phone, and it presents the last DIDs number so no one sees my office line as my callerid anymore. -- Steven Critchfield <critch@basesys.com>
AJ. If it's okay, I'd like to offer my 2 cents. For switch type - it really doesn't matter what you pick, as long as both ends (yours and your telco's) are configured to be same. I don't think anyone has ever noticed any advantages or disadvantages with one switch type over the other. What's more important, however, when talking to your provider is that you tell them that you want your PRI to be able to make long distance calls also. Don't assume this part or you'll only get local calls. For DID - I believe Verizon does offer a block of 25 DIDs. These DIDs will be programmed by your carrier to point to your PRI's circuit ID and it's also known as your LDN (Listed Directory Number). Once these DIDs are programmed, be sure to ask your carrier how many digits they are sending you so that you can configure your PBX to receive that many digits as well. Once your PBX is configured correctly to send and receive the right amount of digits between you and your carrier, you're now need to program these DIDs and associate them to your LENS (Line Equipment Numbers - in the NEC world), hand them out to your users. (I believe Asterisk (in fact, all PBX) can accomplished this task easily. Look at the extension.conf area. (This is just a guess on my part. I too am new to Asterisk.))

DID's on Asterisk are seen as extensions.

Your Verion Rep is way out in left filed. DID is about the only way to go on PRI's. And doing it is about 3 lines in the CO switch. DMS 500 Table DN Route: Numbers to OFRT 223 table OFRT 223 Trunk Group Name table trkgrp Trunk Definition. That is all there is to it. Routing a single number to a PRI channel on the other hand is a nightmare. We sell DID's in upstate NY for about $20 a hundred. Some one else said it. Get a new Verizon Rep. I have about 6 PRI's going to * boxes in my CO right next to a DMS-500, so I know for a fact this works quite well. As a note, while ISDN Q.931 does call for a 10 Digit Called Party Number (PRI DID) it is entirely possible to send 3,4,5 etc digits as the Called Party Number. Stick with the 10 digits. More typing, but well worth it.
