See the new on-demand webcast featuring Q&A with Cisco and Verizon experts.
Secure, Reliable Voice Calls over Your Network
IP telephony transmits voice communications over the network using open, standards-based Internet Protocol.
It provides a way for you to extend consistent voice communications services to all your employees in their workspaces -- on the main campus, at branch offices, remote, or mobile.
Cisco IP telephony solutions are an integral part of Cisco Unified Communications, which unify voice, video, data, and mobile applications on fixed and mobile networks. Your employees can talk with each other using almost any media, device, or operating system
Using your network as the platform, your organization can gain the inherent benefits of a converged network for transport and interconnection. IP telephony makes it easier to:
- Provide highly secure, reliable, scalable communications that take advantage of your LAN and WAN
- Improve employee flexibility and productivity with the full range of Cisco Unified Communications and third-party applications
- Take advantage of a wide range of Session Initiation Protocol (SIP)-based capabilities
