An arrangement that includes at least two PBXs interconnected by a netwo rk employs CTI ports to control operation of the PBXs. Through such control, a user can set up a telephonic presence in a visited PBX such that, to the user and to all others who interact with the user, it appears that the user is at the user's office, rather than at an office that is served by the visited PBX. This is effected by forwarding calls that are destined to the user at the user's office to the visited PBX, and by translating all dialing commands of the user at the visited PBX, and acting upon the translated commands, so as to provide the user with the features available to the user at the user's office while presenting an appearance to called parties that the user is at the user's office.
