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

Hi list, upgrade to 5.1.2 broke my setup due to some different
behaviour in rtpengine.so.

I use:

rtpengine_manage("DTLS=off ICE=remove");

1. I don't send any rtpengine_manage flags (RTP UDP SAVP). UAC sends
RTP/SAVP in SDP, rtpengine changes to UDP/TLS/RTP/SAVP.

Reverted to 5.1.1, and see that rtpengine sends RTP/SAVP

2. To SDP body, rtpengine is adding:

a=setup:actpass
a=fingerprint:sha-1
D6:D7:DA:AA:2D:DB:AD:94:29:46:FA:C4:D8:AE:0F:03:96:6F:8A:4F

For some reason this broke FreeSWITCH which does not like this.
