We use Freeswitch in the case of a SIP to WebRTC application and it is a solid and reliable solution.

 

When we test calls with the sipjs.js library (V0.15.10) and Freeswitch (FreeSWITCH Version 1.8.5-6-31281a0bf1~64bit (-6-31281a0bf1 64bit)  + Debian 9, with the beta version of Chrome, Version 81.0.4044.17 (Official Build) beta (64-bit), we observe a notification on the javascript console :  “[Deprecation] Your partner is negotiating an obsolete (D)TLS version. Support for this will be removed in M81, around March 2020. Please check with your partner to have this fixed. »

 

The Wireshark trace shows that the DTLS-SRTP exchange is done with DTLSv1.0.

 

What would be the version update to do on the Freeswitch side (or Debian) to avoid this deprecation ?

Is there a configuration to do in our current version?

 

Best regards.
