IP Telephony is the technology for transmitting voice communications over a network using open-standards-based IP. Enabled by Cisco AVVID (Architecture for Voice, Video and Integrated Data), Cisco IP Telephony solutions use a single network infrastructure for the transmission of data, voice, and video traffic, delivering the business benefits of a converged network (increased productivity, greater business flexibility, and reduced operational costs) to enterprise-level organizations.

With Cisco IP Telephony, you have a comprehensive suite of IP-based hardware and software solutions to choose from that scale to meet your needs. In addition, this suite of solutions can integrate with existing systems to help you migrate to full IP Communications and protect your technology investments.
