Richard, me too - there's nothing in Help, nothing I've found online, except
this post.

Anyone know of an Idiot's guide, or any other advice?

I just put in a cheap modem, having finally discovered it doesn't work over
broadband, and made my first succesful call! - but only from Contacts.

So Brian, it doesn't seem true that it expects a modem the other end.

I don't understand Dialing PropertiesEdit etc. From UK, I want to prefix
18185 before international, 0845, 0870 and calls to mobiles; otherwise prefix
1899. And my antivirus tries to block every call - till I tell it to allow
all calls to this no.

All advice gratefully received.
