See if you have an IP PBX at work. If you do then all you usually need is a user or SIP license and they can build you an extension. Then you’re on the company PBX.

Yeah, no PBX here - I work alone...:) So I "built my own" International PBX via cheap VOIP (My Divert) and Skype so that I can have an International presence wherever I am. Run a common client on everything so I don't have to learn a bunch of different UIs and it's been quite functional for me.

VOIP on portable devices simply rocks! I'll check out Bria... Looks like a pretty nice option!
