just seeking a little guidance

I have a task to try and get various PBXs in our organisaiton talking to one another. I have CS1000 and BCMs around and a few IP Offices as well. I was going to start using NRS on the SS to manage the call routings to begin with, I was also thinking of giving each site a 3 digit prefix so for example site A has a code of 111 and site b a code of 139. If site A wants to call extension 4534 on site B, the number to dial would be 1394534. Question - can this be done with the help of NRS or do I need to build CDPs and routes between each to each site or can I use a combination of NRS (for when I can just redo a PBX to work thus) and direct routes between switches (for whenever I cannot use NRS).

What is the AC1/AC2 access code? I will suggest to use Location code and make digit 1 as your AC1.

What type of trunk does the PABX connected?

WE have 7 sites that are networked together via H323 trunks. We use CDP and NRS to route the calls. Each site can call the other sites dialing the 4 digit extension of the person you are calling. In your example, when site A dials 4534, if the digit 4 is unique to site B, then at site A you would program the "4" as the CDP and point it to the route that connects to site B, if "45" is unique, then "45" would be the CDP, etc. You would need to enter the CDP digits in the NRS and point it to the Site B gateway, if I remember correctly. You need to make sure you have a unique numbering plan between sites, it will make the programming a lot easier. In answer to your question, you can use the location codes or CDP. I have not used location codes before, as CDP has been easiest for us. Either way, you would utilize the NRS and LOC codes or CDP.

The dialing plan you are describing is called UDP (Uniform Dialing Plan) in the CS1000.

UDP is very easy to set up, and requires the least amount of programming in the NRS - You configure an endpoint for each site, then define a routing entry with the location code for each site.

I know this will work, as I had a couple of BCMs in my network configured this way, until I upgraded and replaced them with small CS1000E's.
