Snom 320 Summary

Snom 320



Ideal for the office and everyone who spends a lot of time on the phone, the snom 320 is an affordable, yet powerful SIP business phone with built-in, full-duplex speakerphone and three-party conference bridging.

Why use Snom 320?

The snom 320 is remote-manageable and firmware-upgradable, uniquely easy to install, and largely self-configuring. Broad codec support and full compatibility with current SIP recommendations ensure interoperability; support for STUN (NAT traversal), ENUM (for dialed-number resolution) and other state-of-the-art features enables flexible deployment behind local proxies, IP PBXs r hosted VoIP services.

The snom 320 supports the security standard SRTP – a current specification from the Internet Engineering Task Force (IETF) for protection against eavesdropping – and TLS for protection gainst sniffing of signaling and authentication data. By limiting the need for external conference bridges/media server capacity or use of conference services for routine multiparty calls, the snom 320’s built-in three-party conference bridge helps limit total cost of ownership, while also ensuring high audio quality and low latency.
