Phones exist (my Nokia E61i can do this). However, if you get the
phone as part of a contract, you need to ensure the VoIP has not
been disabled by the supplier -- some were doing this but I haven't
heard recently. Probably need to ask this in uk.telecom.mobile.

The other warning I would give is that the IP/WiFi and possibly SIP
implementations in all mobiles is rather beta quality compared
with the quality of implementations you may be more used to in
computers. I.e they don't always work, or don't always work as
you'd expect them to. Across a number of colleagues, we've used
most of the IP/WiFi phones (although I've only used the E61i),
and they're all lacking in software quality.

Works for both receiving and making calls for me. I run my own
SIP service for the extended family, and it's only used for calls
between family members, although I can also redirect my home phone
to it over VoIP.
