The Internet2 Presence and Integrated Communications (PIC) Working Group succeeded in an experimental communications trial at the just completed JointTechs meeting. The trial demonstrated SIP-based (Session Initiation Protocol) voice, video, instant messaging and voice conferencing services over an 802.11 wireless network in the context of rich presence derived from conference calendaring and HP labs location server. Participants downloaded and installed one of several integrated communications clients onto their laptops and PDAs allowing them to initiate communications to other participants using the receiver's email address as a single, converged electronic identity. With the inclusion of rich presence services, participants were able to see not only whether attendees were online or offline, but their locatiions and communications state as well.
