I asked freetalk some specific questions, but they just
said "we'll call you back" and never did.

1. For incoming calls, is the Freetalk adaptor working as a server,
listening for incoming connexions ? Do I thus have to have a fixed IP
address ?

2. Can I make computer-to-computer calls (assuming both are Freetalk
subscribers) or do I have to use a third party (Freetalk) ?

3. Can you really connect a BT caller display device to its telephone
port and get meaningful CLI ?

4. Does the Freetalk adaptor use their proprietary protocols ?

No need for a fixed IP address as far as I am aware. I do not have one and
it works fine

If both are Freetalk subscribers you can call using the phone number and the
call is free, why you wouldant to make pc to pc calls I do not know

See other answer, not tried myself

The whole point or a registrar is to keep track of who is using what IP.
You should be able to call any std. SIP device, without either of you being
registered with anybody, just by the router IP number.
Start with hash, replace . with * end with hash.
e.g. #123*45*67*89#
Haven't got a Freetalk, so I can't swear that it works with their service.

Martin

If they have said that to me and then did not, then I would not even
think about having anything to do with them.

I thought the Freetalk service was SIP based.  So shouldn't that be
'nope'?

What if (as is usually the case) the SIP device is on a private IP behind
a NAT router..? Mine is on 192.168.1.20 and has 2 phone ports, how would
you address the individual phones, if my public IP is dynamic and changes
every time I reboot (and sometimes more often, it seems to do it by itself
on occasion..!)

That's why SIP (analogously to H.323) has provision to "register" with
a server (in H.323 it's called a "gatekeeper"), which maintains a
permanent identity by which you can be called, even though your IP is
changing.

People wanting to call you, will call you by means of your identity at
the SIP server.  The SIP server will then direct their client to your
currently registered public IP and appropriate port number (which your
NAT gateway will forward to the appropriate private IP address).

That's roughly how it works.

So how would I go about doing this..?

I can't speak specifically for Freetalk, but normally, when you sign
up with a SIP service, they give you some data to configure into your
SIP client, including their SIP service domain and your SIP number,
and the Internet address of their server.

You configure this into your SIP client, and then, when you
are running the client, it registers itself with their server,
and you can be called by anyone via your SIP "URI"
(sip_number@sip_service_domain), no matter what your IP happens
to be at the time, even behind a NAT gateway.

Google suggests
http://www.zyxel.com/support/suppor...lumbia.edu/sip/ as a starting point for all kinds
of information.

hope that helps a bit.
