The UMEC Wireless IP Videophone SY832 is an easy-to-use handheld device with IEEE 802.11g that provides comprehensive voice communications such as Voice-over-IP (VOIP). It also allows simultaneous voice, video data support on the same wireless backbone. SY832 use SIP RFC3261 as its signaling protocol, which has evolved to become not only a protocol for deploying enhanced voice and data services, but also the future choice of how service providers will trade voice traffic for basic calls and enhanced services.
