well, if you want to give 100 dollars for a 10 foot piece of croconnect wire, i will take it.
The output of a ATA 186,UBR924 or any gateway like that is identical to the normal line that the phone company will provide via cooper cable.
If you have a PBX or KEY phone system connected to normal phone lines, chances are that you have some empty ports on it for normal phone lines.
Just connect the output of the ATA 186 to the “PSTN” or “C.O.” trunk ports of the phone system.
Maybe you will need a RJ11 block to convert the modular cord from the ATA to crossconect wire that you could “puch down” on the blocks of the PBX equipment.
But what the heck. For 100 dollars per line I will supply the RJ11 blocks too.
Now, if you have not bought the boxes yet, I will sugest that you take a look to Ericsson web 100 boxes.
There is guy on ebay selling two for $219 dollars. Seems to have a unlimited supply of them.
Those boxes will give you four ports and it does not need a gatekeeper, only public I.P. addreeses on both ends.
The box is setup via web browser, takes about 10 minutes to setup each and the audio is incredible good.
You could link up to 99 locations that way.
The only trouble: You need to manually program each box to “know ” that there are other boxes out there.
But for $240 dollars, you could connect 4 phone lines betwen offices or locations.
Remember: It does take public ,fix, I.P. addresses on both ends.
Specify how many pieces of wire you will need.
I will forward the invoice……….
