For reasons I need to know how well it works when a SIP client is logged into the same account/number from multiple machines and locations.

For the same reasons I don't have enough time to actually test this.

Does anyone know off the top of their heads?

I.e. I want my home ATA, my work machine in the factory and my mobile logged into the same account and no matter which one I'm using at the time I want to be able to receive calls on the same number.
