FAQ/How can I enable media encryption on my snom phone

From Snom User Wiki

Answer

To enable encryption on your snom phone please set up the following parameter via the phone´s web interface:

RTP Encryption:on

This will enable the phone to offer/answer media encryption parameters.

Note

• The phone will only resort to secure media (SRTP) if the peer UA also supports the same set of media encryption protocols.
• snom190 and snom3XX use different incompatible encryption methods:

• snom190: RFC 3261, k header
• snom360: RFC 3711 SRTP ecncryption algorithm AES
