Hello,

I have 2 SPA-3102 units and I am trying to configure them so I can
make p2p calls via a private LAN and have analog phones connected to
both of them sharing a single POTS (for incoming and outgoing calls)
line connnected to only one of them.

Hardware and connection I curently have:

1) Two spa-3102 each with an analog phone connected to them
2) One of the spa-3102 is connected to a POTS phone line
3) Both spa-3102s are connected together via a private wifi LAN

What I would like to be able to use this for:

1) make p2p calls between the two analog phones connected to each
spa-3102 kind of like an intercom
2) incoming calls on the POTS line should ring both analog phones on
both spa-3102s
3) Both analog phones should be able to make outgoing calls using the
single POTS line connected to one of the spa-3102

Before someone asks, the reason for all this is that each spa-3102 is
in a separate building that cannot be wired together but they are
linked with a wifi network and I want the two building to use the one
POTS line available in only one of the buildings and have the
possibility to communicate p2p between the two buildings.

I am new to VOIP and have spent a couple of days searching for info/
tutorials on the net but cannot find anything similar to what I want
to do. The wizards I found all assume you use a Voip provider in some
way.

Any help/pointers  tutorial or book references appreciated

Thank You

Patrick Robin

Thank You,

I found this link yesterday evening and it did work and give me item 3
and half of item 2 in my features list above. For those who might try
something similar, what gave me the most trouble initialy is that I
could not use the SPA-3102 ethernet ports to do this. I had to connect
both of them to my LAN using the Internet ports and then I don't use
the ethernet ports on the SPA-3102. To me that was counter intuitive.
