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

Thu Feb 4 14:03:05 UTC 2021

Hello, I asked that before, but perhaps the question was somehow wrong
formulated or I didn't provide the right details. My Problem is the
following:

I have a freeswitch 1.10 installation, you can find the container I
use, including a configuration similar to mine, here:

https://github.com/gidmoth/freeswitch-container

(The readme in the etc-freeswitch folder is the one provided by the
freeswitch-minimal config package in debian, but please look at the files
themselfes, because I took that only as a startingpoint).

I have mod_verto enabled and try to connect clients with verto
communicator, build from the sources in the 1.10 release branch on
signalwire/freeswitch (https://github.com/signalwire/freeswitch).

It works perfectly well with chomium-based browsers, but with firefox it
does not work.

>From the logs it is clear, that firefox seems not to start the
negotiation of a key for srtp, and then mod_verto refuses to execute the
call, because the dialplan requires srtp. Here the relevant log, a
failed attemt to call a conference with firefox/verto communicator as a
client:

My question is: is there anything I can change to make it work with
firefox. Any hints welcome.
