Support for SIP redundancy is offered. For example, the WPU7700 is enabled to communicate via a SIP server installed at a branch office if/when the main office SIP server should ever go down. Installing secondary SIP servers where appropriate ensures a secure communications path even in the presence of failure.
A built-in site scan feature enables you to measure signal strength. Use this information to find the best access point, and plan your access-point layout.
Use a PC browser to configure or view the IP settings and other information from your WPU7700. This permits an efficient and responsive WiFi phone management.
Use the WPU7700's Presence feature to quickly ascertain the situation of the people you communicate with (e.g. whether they are out of the office, in a meeting, or out of town on business). No longer must you call to find out, or head to their office to check.
Support for instant messaging is available, enabling you to send and receive short messages in real time. Quickly send required information any time, without worrying about the other person's availability.
The WPU7700 has powerful security features conforming to such standards as WEP (64 /128 bits), and IEEE 802.IX (MD5/EAP-TLS), in order to prevent information leaks in a wireless LAN environment. The WPU7700 provides support for WEP, 802.1x EAP-MD5 / EAP-TLS / EAP-TTLS / PEAP, WPA-PSK, WPA2-PSK, 802.11i Enterprise and Secure RTP. Authentication via 802.IX (EAP-TLS) achieves secure communications using electronic certificates issued by VeriSign Japan. Communications encryption and prevention of terminal spoofing allows you to access communications comfortably and securely in any environment.
Capacity is 3.7V 1300mAH Li-ion with Call time up to 5 hrs with Standby time up to 70 hrs (per manufacturer). Minimum battery charging time is 3 hrs for recharging and usability. The charging state, temperature, signal strength, and other environmental conditions, function settings, etc, may shorten the call time and standby time. Talk and stand-by times are estimated (when using access points supporting a power-save mode).
