Graeme, I do this thing all of the time with Asterisk.
Unlike many other solutions, Asterisk allow you to do it regardless of the
protocol/hardware information you require.

I wrote some API for it for lnet (didn't released it though, but willing to
release it as lgpl), and told Ales about it.

Or use a "click to call" solution for that, and by a push of a batten in a
form you can connect the client's number with your office (I have a client
that I made it for him 3 years ago, and it's part of the services it's
company provides).
