These are frequently asked questions for general telephony:

1. What is Unified Communications (UC)?

Unified communications (UC) is the integration of real-time communication services such as instant messaging (chat), presence information telephony (including IP Telephony), video conferencing, call control and speech recognition with non real time services such as unified messaging (integrated voicemail, email, SMS & fax). UC is not a single product, but a set of products that provides a consistent unified user interface and user experience across multiple devices and media types.

UC also refers to a trend to offer Business process integration i.e. to simplify and integrate all forms of communications in view to optimize business processes and reduce the response time, manage flows, and eliminate device and media dependencies.

UC allows an individual to send a message on one medium and receive the same communication on another medium. For example, one can receive a voicemail message and choose to access it through e-mail or a cell phone. If the sender is online according to the presence information and currently accepts calls, the response can be sent immediately through text chat or video call. Otherwise, it may be sent as a non real-time message that can be accessed through a variety of media.

2. What is SIP?

The Session Initiation Protocol (SIP) is a signalling protocol used for establishing sessions in an IP network.

You may be rapidly reaching the conclusion that everyone has too many devices, too many numbers, and too little time. Session Initiation Protocol is here to save the day. The SIP protocol is fast becoming the standard for complete service integration. Learn how the session initiation protocol can improve software communications architecture while simplifying your device-centric world.

Communications today are devic-centric. Every device has its own phone number, address, or alias. The more devices people use, the more addresses you need to remember in order to reach them. And without presence, communication becomes a guessing game when trying to connect with people on whatever device they may be using.

With SIP, communications become user-centric once again. A SIP address of record or AOR, provides one unifying identifier that can be mapped across multiple devices and media types. With SIP, you no longer need to track multiple phone numbers, e-mail addresses, and IM contact names. SIP will do it for you.

Even more exciting, both users and applications can access presence information, providing the opportunity to create next-generation converged communication applications. For example, your network can deliver new capabilities such as polite calling. Based on information from her calendar application, voice calls to an executive can automatically be routed to an assistant if the executive is in a meeting.

3. What is VOIP

VOIP is Voice over Internet Protocol. VoIP refers to a way to carry phone calls over an IP data network, whether on the Internet or your own internal network. A primary attraction of VoIP is its ability to help reduce expenses because telephone calls travel over the data network rather than the phone company’s network.

4. What is IP Telephony?

Encompasses the full suite of VoIP enabled services including the interconnection of phones for communications; related services such as billing and dialling plans; and basic features such as conferencing, transfer, forward, and hold. These services might previously have been provided by a PBX.
