IP telephony provides a way for you to extend highly secure, reliable, and consistent communications services to all your employees whether they are in main campus locations, at branch offices, working remotely, or are mobile. IP telephony transmits voice communications over the network using open-standards-based Internet Protocol.

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 enabling users to easily communicate in any workspace using any media, device, or operating system. Using the network as the platform, Cisco IP telephony solutions help organizations of all sizes realize greater security, resilience, and scalability in addition to the inherent benefits of using a converged network for transport and interconnection.

Introduction to Cisco Unified Communications
Top Ten Considerations when Evaluating Unified Communications Solutions

Unified messaging (or UM) is the integration of different electronic messaging and communications media (e-mail, SMS, fax, voicemail, video messaging, etc.) technologies into a single interface, accessible from a variety of different devices.  While traditional communications systems delivered messages into several different types of stores such as voicemail systems, e-mail servers, and stand-alone fax machines, with Unified Messaging all types of messages are stored in one system. Voicemail messages, for example, can be delivered directly into the user’s inbox and played either through a headset or the computer’s speaker. This simplifies the user’s experience (only one place to check for messages) and can offer new options for workflow such as appending notes or documents to forwarded voicemails.

Cisco IM and Presence consists of many components that enhance the value of a Cisco Unified Communications system. The main presence component of the solution is the Cisco IM and Presence Service, which incorporates the Jabber Extensible Communications Platform and supports SIP/SIMPLE and Extensible Messaging and Presence Protocol (XMPP) for collecting information regarding a user’s availability status and communications capabilities. The user’s availability status indicates whether or not the user is actively using a particular communications device such as a phone. The user’s communications capabilities indicate the types of communications that user is capable of using, such as video conferencing, web collaboration, instant messaging, or basic audio.
