[jitsi-dev] Jitsi-VideoBridge: DataChannel and BUNDLE

#1

Hello,

Jitsi-VideoBridge works great with PLAN B/Unified PLAN.

I am not clear on the data channels, it looks like only port 5000 is currently supported in the Jitsi VideoBridge.

https://github.com/jitsi/jitsi-videobridge/blob/master/src/org/jitsi/videobridge/SctpConnection.java#L945

SDP example:

m=application 1 DTLS/SCTP 5000

a=sctpmap:5000 webrtc-datachannel 1024

So does a=rtcp-mux has any effect on the data channel? Is it possible to bundle the datachannel as well?

What about Firewall restrictions when port 5000 is blocked?

Best,

Andi

Port 5000 is used only in Sctp stack logic and has nothing to do with
UDP/TCP ports used in the actual transport. Enabling bundle also
bundles the data channel.
