Hmm, it's a bit clearer. The thread is mostly about changing to UK settings
which I didn't really want to do but it does explain why I don't get 2 busy
or NU signals;

"... the 'old' PSTN network always relays the remote ringback tone. (This is
also true for VoIP to PSTN calls.) This is standardized in (inter)national
trunk protocols. The voicepath is opened when a number is available and
ringing. Why? It it weren't, there would be no guarantee that a voicepath
would be available when the called party actually answers.
If you do hear a local ringback tone, you must have hit a VoIP number, as
VoIP never generates a remote ringback tone."

I had thought about clearing the US ring tone settings so the phone
generated silence and all I would hear would be UK ringtone but if I believe
the above this means I would get no tone at all for a voip-voip call.
