Tony K Dan Hi there! I'm not an engineer, I'm a customer support agent, but in my understanding - we had some problems with our servers. The servers were overloaded all the time due to some users running "Batch Jobs" including thousands of calls, and this is why there was an issue with "choppy" calls. We had to add a limit on a maximum amount of active batch jobs per team, and we increased our servers' characteristics by giving them more memory (RAM), and increasing the number of active CPUs, and we made a few more technical changes to ensure the quality of calls. I hope this helps!
