We haven't seen any significant outages in the U.S. since clients transferred to Microsoft 365 Business Voice. With Skype for Business, Microsoft has been offering telephony for years, building Microsoft Teams Voice on a newer service iteration. It's a very reliable, robust platform and is something that Microsoft is continuing to invest a lot of money into. It is ranked highly among cloud-based phone systems, and Microsoft is considered a leader in the UCaaS (Unified Communications as a Service) space.
