[SR-Users] 5.1.2 rtpengine regressions - broke working setup?

[Daniel-Constantin Mierla]

Hello,

what UAC is there and what version of freeswitch you are using?

According to RFC 5764 the token shall be UDP/TLS/RTP/SAVPF:

    8 Session Description for RTP/SAVP over DTLS

    This specification defines new tokens to describe the protocol used
    in SDP media descriptions ("m=" lines and their associated
    parameters). The new values defined for the proto field are:

    o When a RTP/SAVP or RTP/SAVPF [RFC5124] stream is transported over
    DTLS with the Datagram Congestion Control Protocol (DCCP), then
    the token SHALL be DCCP/TLS/RTP/SAVP or DCCP/TLS/RTP/SAVPF
    respectively.

    o When a RTP/SAVP or RTP/SAVPF stream is transported over DTLS with
    UDP, the token SHALL be UDP/TLS/RTP/SAVP or UDP/TLS/RTP/SAVPF
    respectively.


Can you try adding transport-protocol=RTP/SAVP ?

I will try to see what solution can be added to make it flexible to work
in both cases...

Cheers,
Daniel
