I suggest you setup an iPBX with SIP accounts, Setup freepbx installation on a good enough server.
Then add extensions through the browser GUI for each iphone/blackberry/andriod etc and set this up with each phone application. You can add trunks etc from a betamox or google voice if you like and you can call other extensions for free. Obviously your going to be charged for data services etc which are paid usually for anyway.
Worth it if he wants to call from a dial inbound number (from voiptalk.co.uk etc) and not pay high mobile rates.
Recording calls both outbound and inbound are not a problem. You can also have this automatically done or manually record by a code during a call. You may need to tell callers though.
Hope this helps
