Off-premise PBX extension via IP? Kyle 09-02-06

We have four incoming lines and four stations and we'd like to
replace the old small PBX we have now. One feature I'd like
to have is to add a station to this system at my house.

I have broadband internet connections at the office and my
house, so this would be an ideal connection method since it
would eliminate the need for Rube Goldberg-type circuits and
modules from the phone company.

A lot of the material I've found on contemporary PBX systems
refer to their "VoIP" features, but it seems to apply to the
CO connection side rather than the station side.

The IVX C-Class is one example of a system which seems
to be what I'm looking for -- a system that takes traditional
copper connections on the CO side, and accommodates the
usual wired stations plus the option of remote stations via IP.

A similar thread I found in here mentioned the Panasonic TDA50,
but it looks like a "VoIP on the CO side" system (none of the sets
are IP sets,) and it isn't available outside the closed Panasonic
channel anyway.

I'd like to have a set that I could just plug into an internet connection
at my house (or hotel if I'm traveling,) and have it become part of
the system, complete with line and station appearances, intercom
functionality, etc.

If anyone has specific system recommendations, I'd be happy to
hear them!

Thanks.

If all you want is an analog extension to your house off of your PBX at work
you can get 2 small single line gateways
(http://www.sipura.com/products/spa3000.htm) (1 FXS and 1 FXO) and get what
you need. It would be simpler if you have a static IP at your house but
there are ways around that even if you don't.

Program up one analog station circuit on your PBX and plug that into an FXO
gateway then poin that gateway at you rIP address at hoome and there connect
the FXS gateway to your network and then connect an analog phone to it.

Thanks for the tip. So, if I get the Panasonic KX-TA624 switch and some
KX-T7736 sets, I can use a couple of the Sipura units (connect one to
one of the station ports on the switch) and remotely connect one of the
KX-T7736 sets over the Internet to the PBX and get full functionality
(line/extension appearances, intercom, etc.)?

No, they'll just give you a remote POTS line.

OK. Thanks. I guess Ray didn't understand my original question.
