OperationFailedException: Offer contained no valid media descriptions

Hello,

I tried to setup the SIP call from pbx to jitsi. I configured everything which required at both side. When I call extension number from pbx then call joined and immediate drop the called. In jigasi file Following error show me when I opened it.

Based on research I need to add following things inside the /etc/jitsi/jigasi/sip-communicator.properties

net.java.sip.communicator.impl.protocol.sip.SKIP_REINVITE_ON_FOCUS_CHANGE_PROP=true
