Our team has been using https://tuple.app for a few months now, and it works really well for us! We've had much nicer video / audio quality since switching. Definitely recommend checking it out if anyone is looking for a replacement!

Apart from the features and performance of Tuple itself, I find the Tuple team to be a HUGE asset. They are extremely responsive to feedback, are always willing to dig into any issues you might run into, and consistently ship updates and improvements and communicate their progress.
