2 main reasons:<p>1. They typically don&#x27;t say &quot;this call may be recorded&quot;, they say &quot;this call may be recorded for quality assurance purposes&quot; or something along those lines. It should be obvious that the &quot;may&quot; here doesn&#x27;t mean &quot;anyone has permission to record it&quot;, but instead it means it might be recorded&quot;.<p>2. You&#x27;re giving a completely uninformed opinion about a legal matter in which you are basically advising people to do something that might break their state&#x27;s laws. Your &quot;common sense&quot; interpretation of a statement does not necessarily have anything at all to do with the actual legality. In such circumstances, you should <i>always</i> assume the worst, which in this case is that it is illegal for you to record the conversation unless you explicitly inform the other party.
