We are having an issue where callers are report hearing "all circuits are busy" or receiving a busy signal when calling our lines. I personally have experienced this issue as well when attempting to call into the office. My Office Manager has spoken to RC technical support who have been no help. This has been ongoing for several weeks and we are getting to the point of cancellation of service as we can't have calls go unanswered. I am hoping someone can help with this issue.
