Toggling audio or video doesn't seem to do anything
Bug description
When in a chat with someone, clicking on buttons for audio/video doesn't initiate call. Buttons stay on and in case of Video, the video shows up locally.
Examining XML console, there seems to be no traffic at the moment of initiating call.
Server settings should be fine, as calling works with some other clients (Jitsi, Empathy). I am using prosody as a server on a machine with direct internet access. Firewall was turned off for testing.
Attached are output of both clients from 'gajim -v' and prosody.log file from the server at the time of testing. Tried Video calling from 'clienta' to 'clientb' at 18:38:39.
Steps to reproduce
Open up contact interaction, try to add audio or video call.
