I have studied PJSIP for a few days, and now I know how to establish an ICE based media connection for basic audio transmission.

What should I do if I want to send some custom data (arbitrary bytes, which may be very long) using an established ICE transport? -------------- next part -------------- An HTML attachment was scrubbed...
