Hi all! We have a WebRTC user-agent (using sip.js) that is giving me headache.
When a different user-agent calls this user-agent, we frequently see Asterisk generating SIP INFO messages with Content-Type: application/media_control+xml Content-Length: 178 <?xml version="1.0" encoding="utf-8" ?> <media_control> <vc_primitive> <to_encoder> <picture_fast_update/> </to_encoder> </vc_primitive> </media_control> In the payload, that is sent from Asterisk to the caller UA (the WebRTC client is the callee). While this does not do any harm usually, I have no clue yet what causes Asterisk to generate these INFO messages. I do know what they are for (https://datatracker.ietf.org/doc/html/rfc5168), but not why Asterisk is generating those or what might be the trigger. Anyone have any hint? Thanks and best regards FLORIAN FLOIMAIR Symphony Cloud Services (1568)
