Hi guys,

Just wondered if anyone had suggestions around this or had this issue before, we have 2 web clients using the sip.js library and we are trying to use the data channel to send messages to one another.


If I bypass media and send media peer to peer it works fine, however if I try and send an invite with the data channel defined;
m=application 52004 UDP/DTLS/SCTP webrtc-datachannel


Freeswitch seems to consume this when bridging to the target end point/user. Does freeswitch support SCTP/ webrtc-datachannel if I wanted to present it from leg A to leg B so the media can flow via freeswitch?


This is using debian:buster container.


Thanks


Jon

Why don't you use the MESSAGE sip method (supported by both freeswitch and sip.js)?
You can even process the MESSAGE into freeswitch's chatplan, if needed.

Hi Giovanni,

Thank you for the reply, yes good point I saw you implement that in the cookbook some years ago  


I was just interested in using the data channel but you are right I could just use that for chat.


Thanks

For background, I was looking to send status events like isMuted via the data channel for client status, I assume same can be achieved using MESSAGE between client applications?
