Heres a bit of an odd one. An outfit we're involved with a small charity
needs to extend their phone line across to the other side of a road
some 100 yards in all. We have got some cheap secure microwave link
units that have a 10/100 type ethernet at either end.

Yes I know they could go VoIP but there are many and several reasons why
they want to keep the existing phone line.

Anyone know if that can be done with an ATA and thence to ethernet and
then to another ATA if that can be done or else would they need some
other gubbins in line with that to act as an exchange of sorts they need
to be able to use that line to make and receive calls on..

The radio link can be considered a a long CAT 5 cable in effect..

Anyone any ideas?..

TIA...

Do they want traditional wired phones on the far end? If this is not
essential a DECT cordless solution may be an option with the base station in
the original site and a strategically placed DECT extender at some point
along the way. That way they could have up to 6 handsets at the remote
location with transfer facilities.

So why don't they go VoIP and keep the existing phone line?

ie. VoIP PBX (e.g. asterisk) with a PSTN card with an FXS port at the
BT line end, then VoIP phones everywhere else (including the other end
of the link)

That then gives them quite a lot of flexability should they need it.

I rather think it's a bit too far and their room is in the basement so
its got to be up on the roof as such .. And that might be a problem
having an external handset type base.

May well give another suggestion a go..

Bit of a complex Historic story Gordon but mainly as its a DDI line on
someone else's PABX !....

I'm trying to get them to understand that sort of concept!..

That's not neccessarily a show-stopper - if you can stick an analogue
phone on it, then it's still just a POTS line to all intents and purposes.

The down-side of-course is cost!

You could sell it as a "black box" solution and not tell them it's a PBX

However I think you can make some ATAs ring a SIP phone directly,
but it's been a while since I've looked... Quick check and I think a
Grandstream HT503 plus a standard SIP phone might work together with some
configuration noodling - might be worth reading up on their manuals...

Pass on that one, we're not allowed near it and quite frankly I don't
what to be as if anything went wrong with it afterwards guess who'd get
the blame;!..

I think this will end up with a VoIP line at the new premises for
outgoing and forwarding calls from their old line..

Even it if were capable, or upgradable, I suspect the cost of doing so
would come close to or exceede a simpler solution...

Go for it!
