I have done the same across 5 family members, spread across 2 countries.

I'm using Solaris x86 to run the SIP server (it comes with ser, an
open source SIP server). I also run an STUN server on it, so those
family members with NAT'ed IP connections can interconnect with the
rest of us. An STUN server needs to run on a server with two real
routable IP addresses, so one of the homes has a routed /29 subnet,
which isn't available from all internet providers. The SIP server can
share one of these routable IP addresses (actually, I have it on both).
You can probably use a public STUN server somewhere, and of course
there are commercial SIP servers around, but then you are getting
away from running a "dedicated personal VoIP network" which you
wanted to.

For the phones, I use ATAs, Sipura SPA3000's. I decided that if it was
going to work across the whole family, it had to work without leaving
PC's switched on in each household (only the single SIP/STUN server
is left on), and it had to work using the already installed phones,
not some additional separate phone. The SPA3000's all register on
the SIP server, and those with NAT'ed internet connections are
configured to use the STUN server too.

It's all been running for 18 months now, without any problems.

As someone else said, I don't know what specific problems you might
have doing VoIP in India. In some markets, the Voice service is
protected by the State and/or monopoly providers.
