[Freeswitch-dev] ADD 2 ICE CANDIDATES mod_verto

Fri May 29 20:07:05 UTC 2020

Adding the line to the sdp is the easy part.  All the other code to properly handle that we did that is a different story.  Doing it in a way that doesn't impact performance at scale is again a different story.  Setting up split dns so you dont need to do any of that is trivial.
