Buzzering sound on Landline

when i call a Landline there is a very loud noise , it does not exist when i am calling a smartphone

Is this on

no in the selfhosted version

Check the codecs, make sure you enable only the supported codecs and the preferred once and drop the others.

Where can I check them?

Are you talking about jigasi or Jitsi Desktop?


and when calling the Mobile phone i can talk but i can’t hear the conference

The config is in /etc/jitsi/jigasi/

i added this line org.jitsi.impl.neomedia.transform.csrc.CsrcTransformEngine.DISCARD_CONTRIBUTING_SOURCES=true
and now everything works i also disable the opus codec

FYI, This mean that the sip service does not handle RTP correctly.

ah okay good to know i will ask them about that.
does this have any sideffects ?

It just adds rtp extension with cssrc list in every packet.
