VoIP access to home phone? Scott Moseman 09-28-06

Assume I've got a landline phone at my home. Is there any software that
I can setup on my home server that would allow me to use an IP phone to
register with my home server and place calls using my landline? Would
this require something as complex as an actual IP PBX platform? Yes, I
know you can order Vonage (or similar) service and get a wifi enabled
phone, but that's not what I'm asking. ;)

Thanks,
Scott

Asterisk can easily do that, coupled to an ATA with an FXO port such as the
Linksys SPA-3102 to interface the telephone line (the existing phone can be
kept operational by connecting it to the SPA-3102's FXS port).

The SPA-3102 can do that on its own. Easier if your IP phone & your SPA are
connected to the same VoIPSP

Yes, but authenticating the user to prevent calls to the PSTN by other
unauthorized VoIP callers may prove tricky: the caller ID may be faked, PIN
authentication is inconvenient and not so reliable (especially if the VoIPSP
only support inband DTMF), and HTTP Digest Authentication may also fail
depending on the VoIPSP's proxy.

How much more secure would Asterisk be, unless callback was employed? I can
only think of two methods of authentication - by CLID or PIN (Three if you
count both)
