Older system is a bit slow, but works well with our voip service.
We have one of these running at one of our offices. It works pretty well, but is always a bit slow. We were going to get another one, but it looks like it has been replaced by the newer P series Yeastar. So we got that instead. It is faster. By faster, I mean the user interface just navigates and works faster. We have another office with a Grandstream PBX and it is awful. We use Clone Line service at all three locations and we replaced the Grandstream with Clone Line's cloud pbx, and it is by far the best system. We may eventually move everything to that, since it can run all 3 offices on a single system. But for now, the Yeastar works fine.
