Unified communications (UC) is not encompassed by a single product or device. It is a growing category in enterprise networks.

UC is the set of products and services that attempts to provide a consistent single user interface and experience across different media types and different devices.

UC allows a user to send a message from one type of media and have that media received as a different type of media (e.g., leaving a voice mail and having the recipient receive it as an email).

– Unified communications devices.» UC server.

• Specialized servers (which may be virtual in nature) that are designed to implement UC solutions in the workplace.

» UC gateways.• A network device that is designed to translate

between different signaling methods (e.g., a Voice over IP (VoIP) gateway will translate an analog PSTN voice signal into a signal that can be understood on the VoIP network).

» Other UC devices.• Any devices that can be used in the implementation

of a UC solution; they may include (but are not limited to) VoIP phones, email systems, video conferencing, and instant messaging (IM) networks.

– Presence.» An indicator that is used to communicate the

willingness or ability of a user to accept communication.

• Common presence statuses include available, online, offline, busy, and do not disturb.

» Presence services are an important service provided in UC solutions, as they will track individual users across multiple devices (and networks) in real time through the use of multicast transmissions.

• Once a communications session has been established, unicast network transmissions are used.

– Quality of service (QoS).» QoS techniques are implemented to improve the UC by

managing network traffic.• Class of Service (CoS): a QoS technique used to

manage network traffic by grouping similar types of traffic and assigning a network priority to that traffic (e.g., UC traffic is given a higher priority than email). A 6-bit differentiated services code point (DSCP) is used in the IP header to establish the CoS.

VoIP is one of the most common implementations in a UC solution. Through the use of a presence service, calls can be routed to the correct location.

Two important protocols used in VoIP are Session Initiation Protocol (SIP) and Real-time Transport Protocol (RTP).

SIP has two purposes. First, it is used to establish a communication session between two end points. Once the session is completed, SIP tears down the connection.

During the communication session, RTP is used as the transport protocol, helping to provide QoS to the end points.

UC is the set of products and services used to facilitate communication across different devices and media (e.g., transforming a voice mail message into an email). UC servers are specialized servers used to implement UC solutions in the workplace. UC gateways are devices used to translate between different signaling methods (e.g., a VoIP gateway translating an analog PSTN connection into a digital network signal).

Unified communications.

Summary

Presence is an indicator that is used to communicate the willingness or ability of someone to receive communication. A presence service is used to track users across multiple devices and to deliver communication to the appropriate location or device. QoS is set of techniques used to manage network traffic and is often implemented to improve UC.

Unified communications concepts.

VoIP is one of the most commonly implemented UC solutions. VoIP uses SIP to establish and tear down communication sessions. During the actual communication session, RTP is used as the transport mechanism for the communication. RTP helps to provide QoS to the end points.
