Bizarre, do you have some really cheapo headsets or something? (Or let me guess...using your iPhone earpods?) In my role I've tested a lot of pricey speakerphone systems, and we find headset audio quality to be far superior in every circumstance.
no, the issue is that part of the team ends up in one conference room with 1 shitty conference phone. people don't speak up loud enough, don't speak into the mic, etc.. look up cisco ix5000 which is what I'm talking about. it's a whole 'nother beast.
yeah when everyone is on a headset it's fine as long as people mute themselves but when it's a few people on a headset and most in a conference room it's terrible.
Most employees have at least 2 devices with built-in cameras and a screen that can be utilized for videoconferencing.
Give everybody a headset. Done.
