Lifesize for business but not adhoc

We used to use BlueJeans as our main video conferencing system throughout the organisation. However the cost made it difficult to go beyond the original 24 accounts that we had as well as the limit of 25 participants was sometimes problematic for us. We therefore tested several applications and decided at the time to use Lifesize Cloud instead. It was offering more options for a better price. Moving to Lifesize Cloud allowed every user in the organisation to have their own account (100), chat internally and book meetings for each other. But, we have hit a few snags. Lifesize has two main flaws:

1. It is very hard to see who is in the meeting or who is talking. As a result one cannot mute any unique individual so if they are all not very careful to mute themselves, then it can become quite a cacophony. In other words, the moderator functions are very limited.
2. Quality over a less than perfect line is very bad. When we tested, we tested over fairly good connections (100 MB, or 50 at home). The reality though is slightly different. Many are in hotels or in some remote areas and this is where the less than stellar speed is suddenly a problem. Lately, this part has improved but is still far from the competition. As a result, we are have now moved to Zoom.
