To request formatting the solution will send telephone numbers to the activeTAPI Web-Service (via https). The activeTAPI Web-Service may record numbers internally in trace logs without any relation to a person or a customer and only for the purpose of error tracing. We will not use or explicitly persist any telephone number for any other purpose. We neither use or save any person related information. The customer's (company) license key is sent to the activeTAPI Web-Service in the form of the https request header. The information is used to validate the license of the caller.
