Directory Services?

Hi all

I haven't seen anything about directory services interacting with GKs, how would a user know the alias (number or string) of the other party he/she wants to call? Or is there any way for a Terminal user to retrive/search the users currently registered with a GK? And what if the other party is register with another GK?

Thanks
