Dialing Plan Questions

[nooop]

What I find is that if I set up a route, I can only choose certain numbers. For example, site A start DN is 300, and Site B start DN is 200. My destination codes to Site B work perfectly. I have a route for 20, absorb zero and the private recieved is 00. Works great. For 210, I have route 21 absorb 1 and private recieved is 10, works great. We can dial anyone via 3 digits in site B. Problem is reverse, I can not add a destination code of 3, or 31, or 32 etc. Says not valid. I can choose 5 however and it works fine. What is a good rule to go by. I have read that network guide and feel I understand most of this. Do I renumber all DN's at site 1 to start DN of 500 and call it quits? I would assume since the normal start dn of 221 is standard, that site B should start at 321? What am I missing?

Thank You

There are allot of entries that effect the ability to build dest. Codes. For instance, Active DN, Inactive DNs, HG DNs, Line Pool Codes, Call Park Digit, Direct Dial Digit, Recvd. Digits on Target Lines.

You have Active/Inactive DNs blocking your 30, and 31 Dest. Codes. When building a Dialing Plan for multiple locations, 4 digit DNs are a must. Also I do my Startup with a predetermined range that will never be used at any site.

Then if below 4.0 you can use the Wizard to renumber to the range for that site. This allows all your Inactive/ HG DNs to be the same at all sites.

I use the same DN's at every site, they don't have to be different, only the dest code is different.

This is an Analogy so don't take it personally as some have.

Why change the engine if all you need is to change the spark plugs.

Good tips. I will get working, thanks. And acewarlock, what do you use for dest code and start dn if you use the same range at each location? And is your strategy limited to sites? And lastly do you always do 4 digit dialing also? I figured since the office has 10 in one location, and 35 in the other that I would be safe on 3 digit dialing and since the option was available in Element manager, I just did it that way.

Thanks again guys

4-digits or more gives u more number combinations and will result in less chance of conflicts especially once u start to expand.

The BCM (and Norstar for this matter) reserves 640 DNs when it starts up. This means if you start a system at 200, then the ending DN will be ~840, thus not giving you the ability to use 3xx in your dialing plan because it will conflict with your extension range..

I had 60 BCM sites that most used the default of 2221 as the Attn and whe used 6 as the ACOd and a 3 digit location code we got from our company's Finance dept.

So I would dial 6 345 2221 to get the Attn at site 1 and
6 234 2221 to get Attn at site 2. So in our corp tel Dir we would tell everyone to
dial 6
then 3 digit Fin Code
then 4 digit DN

We have our Dest codes start with 6 and a 3 digit Finance Dept code so they would look like

6123
6234
6345
6456
6678
6890

This way where only using the 6 and don't have to worry about conflicks.

My original post was to have 4-digit dialing throughout the company. If your going to add digits, as in prefixes, then disregard.
