Using TLS/Encryption

The Snom C520 is compatible with Call Encryption. However to use it, you need to change some settings in your device:

Ports for TLS

When you enable encryption calls from our system, the ports need to be changed to the encrypted ones. This is just adding " 1 " to the used port, leaving the available ones as 5061, 5081, 42873. Make the proper changes in your device's settings to have it working

Audio Section

Mark this "[]Enable Voice Encryption (SRTP)"
