Group pick up is very handy, if you're with a large bunch of people in a large office, you can get together and say, ‘Right, why don't we answer everybody's telephones if they're not there, let's not just leave them ringing’, Okay, so you get together and you ask me and say, ‘Right, this, this, this, this extension’, it could be up to 40 extensions, ‘We all want to be in the same group pick up’, so what happens is the phone rings, but another one rings.
