GSM, VoIP dual-mode Windows Mobile handset

This Windows Mobile 5.0 phone is designed for Session Initiation Protocol (SIP) VoIP calls that also operates as a regular quad-band GSM/GPRS handset. Dubbed the Hipi 2200, the device is primarily pitched at corporates who want to provide workers with a mobile phone that can also be used for employee-to-employee calls when the device comes within range of the company WLAN.
