HI, everybody! My clients had begun to get the “predator” - crunchy voice sounds and I had to do phone sessions for several days while I figured it out. Doxy.me customer service wasn’t helpful beyond not using Safari! I don’t use Safari nor were my clients - but my Chrome browser and theirs was up to date (only advice Doxy.me gives is be sure to have the most recent updated browser). So, then I went to my Windows 10 update and discovered it had a newer update that did not automatically install - apparently with Windows 10 they aren’t automatic - and after the update suddenly no more problem. Please make sure you have the most recent update on your Operating System as well as whatever Internet Browser you are using!
Hope this helps!
