BYOD stands for Bring Your Own Device which commonly means you should bring your own laptop or other device to a meeting. This was a common way of having meetings when all participants used to be in the same room. Here, you share your display to the other people in the room or if you have a video conferencing system installed in the room you can share content from your device to that meeting.
BYOM stands for Bring Your Own Meeting meaning you also bring your meeting platform, such as Zoom, Teams or Google Meet along with your device. With this way of working, you use the platform you like instead of having an in-room video conferencing system. With Delo connection manager you will be able to access all meeting room equipment such as cameras, speakers and microphones and use them for your meeting, regardless of platform.
