SIP SIMPLE Presence Server

Presence is becoming increasingly useful in our daily lives as our communication patterns have evolved. Metaswitch’s Colibria SIP SIMPLE Presence Server ensures that presence information can be published, shared, subscribed to and propagated while ensuring privacy and a reasonable network load.

Presence provides real-time information about any user, allowing other users or the network to make the right communication decisions. Presence information can be about which devices and services the user can be reached on, as well as information about the user’s location, mood, willingness to communicate and status expressed through text and picture.

Presence underpins the GSMA’s Rich Communication Suite (RCS) and allows Push to Talk over Cellular (PoC) users to see who is online. It enriches a VoIP service by allowing users to see who is available and who is on the phone. In multi-device solutions it even allows routing engines to route communications to the location where a user is most likely to respond.

Presence operates anywhere IP access is available, and with the use of Presence Network Adaptors is even able to pick up the presence state of traditional devices like standard mobile phones. All of the above simplifies and enlivens the user experience and promotes communication, driving operator revenues.

The Colibria Presence Server is a carrier grade, fully standard OMA compliant SIP server that controls and manages every aspect of presence. Its Flexibility allows it to be deployed in any SIP and IMS environment.
