2Wire 2000 Series Gateways & VoIP: Most of the late model 2Wire 2000 series gateways provide excellent support for VoIP. Using the single RJ-11 jack available on select 2Wire gateways (2700SGV, 2700HGV, and 270HGV), it is possible to provision VoIP on two telephone lines. Interestingly, the list of VoIP technology standards supported by these little 2Wire gateways is rather impressive -they natively support several standards including: SIP user agent interoperability with Broadsoft Broadworks v11.1, Nortel MCS 5200, and Sylantro servers; Audio codec support for G711 (software upgradeable to G.726 and G.729a), and Voice over Wi-Fi (VoWiFi) support for UMA and SCCAN wireless mobile phones.

Wireless Capabilities: HyperG Wireless capable gateways (2Wire model # 2700HG, 2700HGV, 270HG and 270HGV) as well as other 2Wire 2000 series gateways capable of operating in IEEE 802.11g mode (model # 2700HG and 2700SGV) have an access point that is backwards compatible with 802.11b (wi-fi) standard. Therefore, these devices would be compatible with most wifi-enabled devices -including gaming consoles such as Nintendo DS.

Caution : Potentially Dangerous, Excessive, Harmful RF Levels: These 2Wire devices are capable of radiating very powerful RF signals –all the way up to 400mw of RF power output. Considering that most APs generate less than 100mw of RF, the radiation levels produced by these 2Wire devices can be as much as seven times more intense than most other FCC Part 15 (intentional) radio transmitters. Health risks to those in close proximity (within 3m or 10ft) of such powerful (potentially harmful) RF transmitters can be even significantly higher. Therefore, it may be potentially unsafe (even outright dangerous) to operate these kinds of high-powered radio transmitters blasting away at full power. Radiating excessive amount of RF energy not only exposes humans (and other life forms) to serious health risks; it may also cause radio interference to other RF networks in your area, and potentially make you run afoul of FCC Part 15 regulations. Considering that these devices can be easily configured to operate at 10 different (reduced) power settings, why not lower the RF power output as low as possible and save yourself (and others) from excessively harmful/dangerous RF radiations?
