Hi, I have a problem getting verto-communicator and/or mod_verto running with firefox. It works with chromium-based browsers without problems, but it looks to me (that means: I don't know exactly, but I suspect) as if the ciphersute to get the key for srtp is not perfect-forward-secure. Maybe that's the reason for firefox to fail, but I couldn't find any documented way to change the ciphersuite, neither in mod_verto, nor in mod_rtc (perhaps I oversee something). What I attach here are two logs. The first is the successful call to a conference witch edge (chromium based), the second is the try to do the same with firefox. Both logs begin at the same point, where verto does the state change CS_ROUTING -> CS_EXECUTE, the whole logs only differ after this point. Can anyone help me? In case it matters: the certs are from letsencrypt. __ s.
