The SNOM phone is the only voice over IP desk phone that also includes a VPN solution. For some mysterious reason for which we can but hazard a guess, SNOM does not ship firmware with the advertised VPN functionality, you have to upgrade the firmware. It is not as forbidding as it seems and we are happy to assist you in this process.

Once the VPN is installed, all traffic from the phone to our servers is encrypted, including all calls between VPN connected SNOMs.
