IP Office is a highly modular IP telephone system designed to meet the needs of home offices, standalone businesses, and networked branch and head offices for small and medium enterprises. The award-winning IP Office gives growing companies a complete solution for telephony, messaging, networking, conferencing, customer management, and unified communications. 

 IP Office is a versatile communications solution that combines the reliability and ease of a traditional telephony system with the applications and advantages of an IP telephony solution. This converged communications solution can help businesses reduce costs, increase productivity, and improve customer service. Avaya believes that customers should be supported in migrating to IP telephony at their own pace, following their own path. Clients can use a mix of digital, analog, and IP technology and still take advantage of all the applications that convergence provides.

IP Office addresses basic telephony needs, leverages built-in convergence capabilities, and capitalizes on robust unified applications to deliver intelligent communications to users and customers. This small office IP phone system simplifies processes, and streamlines the information exchange within systems to create simple and effective communication experiences.

The IP Office phone system supports a wide range of telephones, but the Avaya 5400 Series Digital phones and 5600 Series IP phones have been specifically designed to work with IP Office and provide small and medium enterprises with a choice of solutions to meet business efficiency and customer service requirements.
