Use Cases and Deployment Scope
We use 8x8 Express as our phone system. We use it for incoming customer calls, interoffice calling and voicemail. We previously used Comcast, but grew weary of ever-increasing costs. 8x8 Express costs have remained stable since the initial contract was executed. The auto attendant was the next main draw (behind cost) as it let the caller decide to where the call should be directed, not the first person who answered. We discovered some sales calls were being selectively cultivated for one sales person (that's management's call, not the receptionist's discretion).
