Why we record telephone calls.
Firstly, many companies record telephone calls as a matter of course. Smaller companies tend not to do so due to the cost and effort involved.
As a business, we are bombarded with sales and marketing calls. Some of these are scammers.

Our only defence against companies like this is to have our telephone conversations recorded for reference.
