Hi,

I'm trying to get freeswitch to direct a call to a linphone client using DTLS, as described here:

https://freeswitch.org/confluence/display/FREESWITCH/Certificates#Certificates-DTLS

The A leg with a DTLS client works fine but the B leg, while enabling correctly DTLS in the SDP INVITE(fingerprint and setup attributes) produces a media description using the proto "RTP/SAVPF".

Linphone does not accept this proto as a DTLS call but expect "UDP/TLS/RTP/SAVPF". I'm using freeswitch v1.10.6, I found in the freeswitch code there

https://github.com/signalwire/freeswitch/blob/v1.10.6/src/switch_core_media.c#L9715

a test to switch to the expected proto but I can't find a way in the freeswitch settings/dialplan to get the CF_AVPF_MOZ flag on. When forcing the outcome of the test to be always true, I get my particular use case to work but I guess there is a more harmless way to proceed. Any suggestion?

Thanks,

Johan
