[Freeswitch-users] 1.8 DTLS calls

Wed Feb 20 17:34:18 UTC 2019

That seems to be a nat problem, or an ice misconfiguration, like using
wrong stun (that results in a nat problem, again).

I assume all is equal in server.

Check to see if you can give different parameters to clients, maybe between
releases Freeswitch changed in subtle modes how it react to subtle client
parameters. I would check all nat/ice/stun client parameters and experiment
with them...

Just a possible line of investigation, no warranties ;)
