Hi all,
I tried, with liblinphone to place a call top a endpoint without SRTP (SDES) support when my session is configured in TLS with SRTP encryption but not mandatory.
My call fails on Liblinphone side.
It seems it is because the SDP RTP only of the answer is not acceptable here.
If I receive an incoming call with RTP only, it is accepted.
Is there a way to have a fully SRTP preferred configuration, with fallback on RTP when the answer is RTP?
I did the same test with Linphone and have the same behavior.
