This term describes a user who gets their telephony features and services from the local IP Office. IP Office users were formerly referred to as distributed users, local users, or native users.

IP Office users with non-IP phones are connected to the IP Office while IP Office users with IP and SIP endpoints can be administered with IP Office as their controller. Access to and from the rest of the Avaya Aura® network is via the IP Office system’s SM Line, which connects to Avaya Aura® Session Manager across the enterprise WAN. This connection allows for VoIP connectivity to other sites in the enterprise, to centralized trunking, and to centralized applications such as conferencing and messaging.
