ASTRI W-iSIP reference design is a high performance and cost-effective one. It offers a complete turnkey solution for phone manufacturers to make a SIPcompliant, wireless VoIP phone. Together with a complete telephony feature suite, W-iSIP features a solid platform of high voice quality and innovations, which is also highly customizable via SDK.

I. Excellent Voice Quality
Excellent voice quality now becomes a MUST! Featuring voice codecs like G.711, G.729AB, enhanced voice features like adjustable jitter buffer, packet loss concealment and VAD/CNG, W-iSIP leads to nothing but a superbly pleasant conversational experience.

 

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.
