Hey,

How do these work? do you get a range of numbers that get delivered down a circuit? How do your 800 numbers deliver to your sites? do they get overlaid on to delivery numbers?

SI there somewhere I can find this out?

It's not getting any smarter out there. You have to come to terms with stupidity, and make it work for you.
 
it is like ringing assignment on a key system
they do it in there software!!
 
Do you mean DID service, or something else? You can get DID on a circuit, via basic T1 or PRI; or you can get analog DID trunks. These can be delivered in any range of numbers from 1 to 10,000+. Ususally they are sold in blocks of 20, but you can get a few, non-sequential numbers if requested.

800 service in a non-dedicated mode (switched) can be pointed to any DID number, then the inbound call follows the path the DID number would use.

I am not sure if this answers your question or not.

Hope this helps,

Scott M.
 
so do you get a local and a long dist provider etc?

Depending on the area, you could get both from the same provider. We use Qwest for local DID service and AT&T for LD. We have some 800 numbers on switched service, pointing to DID's or main POTS lines; while others are provided into a main location via dedicated circuits from AT&T (this can work like DID, as you point 800 numbers to a 3, 4, or 5 digit number inside your phone system).

Hope this helps,

yes in my case i have verizon as my local carrier
then i picked what outgoing long distance company
i wanted .then i bought a toll free number from
a company that provides that service and they
point that number at my local lines!! hope this helps

i suppose all of these services could be provided
by one company but you would have to do some research
 
MikeyB,

If you tell us what it is you want to accomplish, and your contraints, you will get a boatload of information from mebers of this forum.

For example -

how many trunks?

How many phone numbers?

Analog or digital?

Business or residential

etc.

My point is that there are dozens of ways to get lines from the PSTN even if you don't consider VOIP part of the PSTN. If you add in VOIP the whole thing expands further.

Let us know, and I promise you'll get good ideas from the people on this list.

Good Luck
