[Asterisk-Users] Newbee question

[Chris Lee]

I am new to asterisk and am wanting to know if it can do some things:

in a large/ distributed environment users move about either office to 
office or branch to branch can they log in and have their virtual 
extension routed to the one they are on?

naturaly this implies the question: if branch servers are used can they 
ceep track of where a virtual extension is currently attached?
