FAQs
Avaya IP Office is a unified communications platform designed for businesses with 5 to 3,000 users. It handles voice calls, video conferencing, instant messaging, and voicemail on a single system, and can be deployed on-premise, in the cloud, or as a hybrid of both. Calls are routed through the IP Office server, which manages extensions, auto-attendants, call queues, and call recording. Advanced Communication Systems is a certified Avaya dealer and handles the full lifecycle — design, installation, configuration, and ongoing support — for IP Office deployments across the Mid-Atlantic and nationwide.
Avaya IP Office is designed for businesses ranging from 5 to 3,000 users, making it one of the most scalable SMB-to-mid-market platforms available. The entry-level configuration works well for small offices that need professional call handling without IT complexity. The platform scales to support multiple locations, contact center queues, and thousands of concurrent users as the business grows. ACS has deployed IP Office for organizations across that full range and can size the system correctly from the start so it does not need to be replaced as headcount increases.
