All he needs, at least to start with, is an equivalent to a single BT phone
line with basic facilities, such as answerphone and call divert, a local
(London) number and possibly 0845 or 0870 number. Purely software solution
dependant on a constantly running PC would not be a good idea.
The service needs to be reliable and with voice quality comparable to a
standard BT or NTL line without blips* or other manifestations of problems
with data activities on the broadband connection.
*If it could be arranged that the voice comms takes priority over any other
broadband activity (to suspend it) without the need for human
intervention - that could be acceptable.
Could anyone suggest suitable service but also required equipment. Or
should he get a standard telephone line for the time being?

Well, he'll need a standard PSTN line from BT before he can order ADSL
(I'm assuming that he's not in a position to install SDSL or a leased
line...), so any saving he makes will be on call costs.
Voiptalk will give him an 020 7 or 020 8 inbound number for about £3 a
month, and charge him about £0.01 a minute on outbound calls.
He'll need an ATA box of some sort (they run from about £30 to about
£70) or are sometimes integrated with ADSL routers, and a router that
supports QoS (which will allow you to give priority to voice traffic).
See http://www.draytek.co.uk/products/vigor2500v.html
Here's the expensive part: for *good* call quality, you need packets to
be delivered regularly. The upstream channel of ADSL is 256kbps, and in
a domestic ADSL installation, that may be shared by 50 users. G.729
needs about 14kbps, so you may get less quality than you expected.
A typical "business" ADSL connection has a contention ratio of 20:1, and
you may get away with this for one call at a time. Generally, our
customers buy uncontended (1:1) ADSL connections, but they are running
more extensions than you want to.
If you'd like to give me your 'phone number by email, I can give you a
demonstration.

Well he will need the BT line to get the ADSL, As to saving money it will
depend on his calling pattern. Is he intending to work from home or an
office? If its an office then he needs to look into serviced offices or If
he has just left Uni, Contact them and see if they have a "Innovations"
center (These come under many names but are Uni supported office complexs
for start ups.

If he can get a cable connection then he may well not need the BT line.
The BT analogue line is a requirement for ADSL, but not for all
types of IP connection...
I'm sorry, I know *nothing* about speeds and contention ratios for cable
connections.

I am not sure how well "cabled" London is so I assumed that he will
have to use BT.
