Clearly Cloud USA registration issues

During the early afternoon of Friday May 16, our engineering team detected a potential issue and proactively moved production SIP services onto a secondary redundancy system in an abundance of caution in order to prevent a widespread service disruption. For approximately an hour, the secondary system operated with limited BLF functionality but processed calls and registrations normally. There may have been very brief issues with call setup or registration during the failover and failback process. BLF features were restored to normal functionality at the conclusion of the failback operation.
