[Freeswitch-users] mod_verto, verto communicator working only with chromium-based browsers

Fri Feb 5 14:41:56 UTC 2021

Just for info. We are using verto and it works in Chrome, Edge and Firefox.
Out of the box.

INCOMPATIBLE_DESTINATION could be because of codecs. Try to allow only
pcma, pcmu in verto config. Just a thought to test it...
