Is an On-Premises Phone System Better for Your Business?
For many businesses, an on-premises business phone system offers superior reliability, security, and cost savings. Unlike cloud-based solutions, it provides full control, seamless integration with existing infrastructure, and long-term affordability—making it the ideal choice for organizations that need performance and security.
What Is Avaya IP Office?
The Avaya IP Office platform is a cost-effective telephony system that supports a mobile, distributed workforce with voice and video on virtually any device. IP Office is a modular communications solution that scales up to 3000 extensions and 150 sites in a multi-site network with resiliency.

Match a deployment model to infrastructure needs from simple appliances to virtualized software in a data center with options in between. Improve customer experience and contact center agent efficiency with powerful, affordable multichannel functionality for voice, email and web chat. The solution combines collaboration software plus multichannel contact centers, networking, security and video.
IP Office provides a hybrid PBX with both Time Division Multiplexing (TDM) and IP telephony with trunk support, used in either mode or both concurrently. IP Office has data capabilities built-in, providing IP routing, switching and firewall protection, between LAN and WAN (LAN2).
In addition to basic telephony services and voicemail, IP Office offers both hard phone and soft phone options. Soft phone applications are designed to provide flexibility for remote workers and to allow workers to access telephony services, such as making and receiving calls, voicemail, and call forwarding from their computer or mobile device.
