Premium Rate

Some Companies use Premium Rate services for their helpdesk and customer services. This can mean that you cannot blanket ban all premium rate numbers. Some of the numbers which are deemed as Premium Rate services don’t actually charge that much. So how do you decide which ones to block on your PBX? How do you know who is actually dialling these numbers? Could you negotiate a cheaper rate to these numbers if you dial them regularly? Are these calls evidence of misuse by your staff or fraud from outside?
Why not set up reports which can show you all calls to Premium Rate services including a cost field so you can see the actual cost? Run reports to identify which extension is dialling those numbers and their frequency.
