Did you know that Snom IP telephones have supported both TLS & SRTP for years (they were the first IP phones on the market to do so). Configuring a Snom IP telephone to work with TLS and SRTP is a rather simple task but before you start, make sure that:
  • Hosted PBX Users - Your VoIP provider must support TLS and SRTP for this to work.
  • Onsite PBX Users - Your PBX needs to be correctly configured and have the required certificate(s) installed for this to work.
TLS and SRTP will not work if your VoIP provider or local PBX isn't configured to work with these protocols!

Firmware 8.x:
Snom IP telephones do not verify server certificates by default. If you want to turn this feature on, go to the “Certificates” page in the phones GUI and click “Activate”. You must either use a certificate from a known CA or *import your own CA certificate into each phone manually.

Firmware 10.x:
As of version 10.x, Snom has decided to force the server identity verification. This verification cannot be disabled because that would create a security weakness for the Snom Phones. Again, you must either use a certificate from a known CA or *import your own CA certificate into each phone manually.

*Certificates must be in DER format.
