WELCOME

Thank you for purchasing Grandstream GVC3200/GVC3202 AndroidTM Video Conferencing System. This document introduces the LCD settings, web UI settings and advanced configurations of GVC3200/GVC3202. To learn the basic configuration and how to use GVC3200/GVC3202, please visit
http://www.grandstream.com/support to download the latest "GVC3200/GVC3202 User Guide".
GVC3200/GVC3202 is a ground-breaking solution that offers small-to-medium businesses a revolutionary video conferencing system with unprecedented flexibility and the power of support for multiple popular video conferencing protocols and platforms right out of the box. The SIP-based GVC3200/GVC3202 supports Grandstream’ s robust IPVideoTalk cloud platform for plug and play video conferencing while also being interoperable with any 3rd party SIP video conferencing platform - thus offering a great option to expand or implement a 3rd party platform. Additionally, since it is based on AndroidTM 4.4, the GVC3200/GVC3202 offers full access to all video conferencing apps in the Google PlayTM Store.
The GVC3200/GVC3202 sports an innovative, patent-pending embedded MCU that supports conferencing with local mixing between SIP and other protocols:
The GVC3200 supports 9-way conferencing with local mixing between SIP and other protocols.  The GVC3202 supports 3-way conferencing with local mixing between SIP and other protocols.
In comparison to Grandstream’s GVC3200, the GVC3202 offers a slightly lower capacity option for
businesses looking for up to 3-way video-conferencing and support for up to 2 Full HD monitors.
The GVC3200/GVC3202 eliminates the traditional barriers to video conferencing and sets a new bar for business-class video conferencing solutions by offering industry-leading flexibility, interoperability, system compatibility, application richness and ease of use.
