Other features such as the blocking of anonymous callers, downloading ring tones, the automatic call acceptance or the "calm" function are just a few from a wealth of functions that guarantee calling comfort and increase productivity. Additional applications such as the SNOM CTI solution ESTOS Procall increase the functionality. Installing the Snom 320 is a child's play, and is possible both on the phone and as a distance configuration. Other plus points are the extensive codec support and the great compatibility with SIP components from other manufacturers. The support of Stun, NAT, Enum and numerous other functions enables flexible use behind local proxies, IP PBXs or hosted VoIP services. The built-in three-way conference function of the SNOM 320 lowers their costs and offers high audio.
