Problems solved by technology

When the conference chairman needs to negotiate with the conference center when upgrading the video or downgrading the audio, whether other conference participants should upgrade the video or downgrade the audio at this time depends on whether the conference center will require them to upgrade the video or downgrade the local policy of the audio , because other conference participants cannot participate in the negotiation process, so they cannot know the final negotiation result; when the conference participants upgrade the video or downgrade the voice operation, they also need to directly negotiate with the conference center, and the conference chairman cannot control the process, and at the same time The conference center also does not notify the conference chairman of the current media type of the conference participant, so the conference chairman cannot know the media type of all conference participants accessing the conference call in real time

[0003] It can be seen that in the existing VOLTE conference phone, neither the conference chairman nor the conference participants can know the current media type of other participants.
