2009 OpenWRT was capable of supporting mobile VoIP applications via Asterisk running on a USB stick. As OpenWRT runs on most Wi-Fi routers, this radically expanded the potential reach of mobile VoIP applications. Users reported acceptable results using G.729 codecs and connections to a "main NAT/Firewall router with a NAT=yes and canreinvite=no.. As such, my asterisk will stay in the audio path and can't redirect the RTP media stream (audio) to go directly from the caller to the callee." Minor problems were also reported: "Whenever there is an I/O activities ... i.e. reading the Flash space (mtdblockd process), this will create some hick-ups (or temporarily losing audio signals)." The combination of OpenWRT and Asterisk is intended as an open source replacement for proprietary PBXes. The company xG Technology, Inc. had a mobile VoIP and data system operating in the license-free ISM 900 MHz band (902 MHz – 928 MHz). xMax is an end-to-end Internet Protocol (IP) system infrastructure that is currently deployed in Fort Lauderdale, Florida. 2010 In January 2010 Apple Inc. updated the iPhone developer SDK to allow VoIP over cellular networks. iCall became the first App Store app to enable VoIP on the iPhone and iPod Touch over cellular 3G networks. In second half of 2010 Nokia introduced three new dualmode Wi-Fi capable Series40 handsets (Nokia X3-02, Nokia C3-01 and, Nokia C3-01 Gold Edition) with integrated SIP VoIP that supports HD voice (AMR-WB). 2011 The mainstreaming of VoIP in the small business market led to the introduction of more devices extending VoIP to business cordless users. Panasonic introduced the KX-TGP base station supporting up to 6 cordless handsets , essentially a VoIP complement to its popular KX-TGA analogue phones which likewise support up to 4 cordless handsets. However, unlike the analogue system which supports only four handsets in one "conference" on one line, the TGP supports 3 simultaneous network conversations and up to 8 SIP registrations (e.g. up to 8 DID lines or extensions), as well as an Ethernet pass-through port to hook up computers on the same drop. In its publicity Panasonic specifically mentions Digium (founded by the creator of Asterisk), its product Switchvox and Asterisk itself. Several router manufacturers including TRENDnet and Netgear released sub-$300 Power over Ethernet switches aimed at the VoIP market. Unlike industry standard switches that provided the full 30 watts of power per port, these allowed under 50 watts of power to
