Contacts and history application for Avaya H175 IP Phone

The Avaya H175 Video Collaboration Station is a unique touchscreen device that delivers high quality voice calls, full HD video collaboration, and accessto key productivity enhancing capabilities like presence, a synchronized calendar and synchronized contacts. Solidly built, elegantly designed, and ready to support the way you work for years to come, the H175 helps drive team engagement throughout your organization.

I built the Contacts and History application which is there on this device. I also contributed to the UI development of CommApp(conferencing, call transfer).
