Three com Voice Over IP
Voice Over IP and 3G Mobile technology are set to merge with the introduction of a new breed of handset that can make use of either connection if they are available. A Linux Devices.com article reports that NTT DoCoMo are now offering business subscribers a dual-network 3G/VoIP handset that works as a 3G mobile phone, VoIP (voice-over-IP) terminal, or both simultaneously.
The N900iL handset is based on a Linux-based 3G mobile phone software platform developed jointly by NEC and Panasonic. It can operate as a 3G mobile phone under NTT's W-CDMA 3G network, or as a VoIP phone with SIP (session initiation protocol) control under wireless 802.11b networks. Or, it can be set up for dual-mode operation under both kinds of network.
