Mesh Phone Dial Patterns

Good Morning,

Before our directory gets too big I wanted to have a conversation about extension organization. I had a few questions and wanted to see how others were breaking this down.

What system do you use in your mesh? Is it a guess by golly or well thought out numbering pattern?

Thanks in advance!

Here in Northwest Ohio, we

Here in Northwest Ohio, we have set up the following numbering plan that can be extended theoretically nationwide. It's pretty simple. <State><County><Extension>, so I have 17-48-017, and someone just across the line from me might have 26-58-123. State is just the two digit number, in the order they joined the union, county is the way the state assigns the county number, in both Ohio(17) and Michigan(26), that's alphabetical order. We figured 1000 extensions in a county was probably good around here, but if you're in a really populated area, you could make that bigger. We have one person managing assigning the extension numbers for the region just so we don't have duplicates. If your area would like to adopt similar, you're welcome to. In any case, I recommend talking to others around you to make sure that everything is compatible.

That's a solid option.


That's a solid option.

Any others?

My Approach

On a PBX network I put together called "MeshPhone", we have a 4-digit dial plan for local calling and a 7-digit plan for network calling. Your network number is your 4-digit local number prepended by your Area Code, which most people can readily understand.

Thus, my shack extension is 2111 and my MeshPhone number is 973-2111.

Locally, to call up my NOAA Weather Radio, you dial 2199 and from the network you call 973-2199.

There's about 40 PBX's scattered around the world on the network. International locations use their 2-digit country code prepended by a 0 or 1 plus their 4-digit extension instead of Area Codes which are only used here in the States, Canada, and certain Caribbean countries.

PBX's using 3 digit extensions are prepended by their Area Code and a dummy digit to round out their network number to 7-digits.

Of course, local pbx's can get together and devise their own dialing plan for their community of interest. The main thing is that the dialing plan of one pbx can not overlap the dialing plan of another pbx. And, this can transcend Area Codes. A few years ago I devised a plan for the state of Tennessee which is now working well in practice. 4-digits for the whole state and Area Codes depending on county (mirroring what is done in the telephone network).

We have been using an alphanumeric scheme here.

Example:
KD1HA = 53142
KB1JFG = 521534 
N2MH = 6264
KF7VOL = 537865

How do you deal with dialplan

How do you deal with dialplan collisions in that? We have several pairs of hams in our area with sequential calls because they took our club's tech class together...

Thank's for everyone's info!

Thank's for everyone's info! I think I need to take some time to digest this. In some ways I still need to do some catching up. I going to come back to this once I can get a better understanding of what we are is looking to do. For now, we have four digit extensions which sounds like it will jive with the approach Mark shared

Thanks guys and be safe out there!
