[Freeswitch-users] WSS - DTLS handshake takes about 6s in firefox

[Geoff Mina]

Can you get a Developer Tool console log from Firefox which includes the SIP?

FireFox has a 5 second timeout on ICE candidate gathering.  

I’m wondering if there is a failure is on the ICE side and FF is returning too many srflx records that need to be tried.
