Avaya IP Office is an all-in-one solution specially designed to meet the communications challenges facing small and medium sized businesses. Due to its modular design, the solution can scale from 2 to 360 extensions to meet the needs of home offices, standalone businesses, and networked branch and head offices.

Avaya IP Office delivers full voice functionality with a comprehensive set of features. The system can be configured as a voice-only PBX using traditional circuit-switched lines or as an IP telephony server using high-speed ISDN/PRI dial-up access and/or direct leased line connectivity.

Multiple Avaya IP Office systems can be linked together using a standard data network, providing limited rich transparency and advanced applications such as centralized voice mail and call center
