Strata: user reachability in multi-apps environment

Demo shown as part of the paper presentation titled "User reachability in multi-apps environment" at IEEE ISM 2015. View presentation and paper at https://kundansingh.com/talks.html. The demo video shows the cross-platform Strata app with contacts, video call, conference, mode switch, text chat, multimedia attachment, reachability priority, reachability on external systems like IP office, programmable reachability policy, phone dialer, dynamic contact from calendar for click-to-join the next meeting, interaction among other user devices, and multi-tenancy. Keywords: WebRTC, system design, mobile app, user reachability, multi-services, VoIP, caller policy. Paper: https://kundansingh.com/papers/2015-strata-reachability-private.pdf Presentation: https://kundansingh.com/talks/2015-ieeeism-strata/index.html The paper describes the problem of user reachability in today's seggregated multi-apps environment where an user of one service cannot easily talk to that on another. It also describes the architecture and implementation of Strata, a mobile-first but cross-platform app, that can dynamically figure out the right reachability, and can integrate with bunch of existing services such as phone system, Avaya IP office, Scopia, AMS, etc.
