II.
Power Management
ASTRI W-iSIP phone comes with an efficient power consumption
design. Whenever the phone is idle, various hardware components
such as MCU and WiFi modules automatically enter the sleep
mode to minimize power consumption, resulting in a longer
stand-by time.
III.
High Mobility
Thanks to the innovative across-AP's handoff solution the
phone now supports, having an uninterrupted conversation
with mobility is undoubtedly not a problem at all for the
W-iSIP users. |
