Concerning security, the snom 320 protects you with SRTP and TLS against wiretapping and unwanted access to signaling and authentication data. The snom 320's built-in three-way conference bridge eliminates external devices and services while offering high audio quality and minimal latency. These savings together with the very low energy consumption (1.0 to 1.5 w-hrs in standby) and PoE (Power over Ethernet) of this snom phone truly help to lower your costs.

snom also offers a UC edition snom 320 that is qualified for Microsoft Lync. When registering a snom 320 UC Edition you will create an easy mass configuration and customization of the snom VoIP Phones. These snom UC Edition phones allow the Microsoft Lync user to now fulfill any business needs with a VoIP Phone.
