Zoom Phone: can't get rid of "call may be recorded" prompt on one number

Please help.  When a call is made or picked up from just one phone number under my account, it triggers the prompt "This call may be recorded for quality assurance."  I have no call recording enabled on any account, so please don't direct to the instructions to turn off the toggles for recording and ad hoc recording. Has anyone experienced or does anyone know how to disable?  Again, it's only happening on one phone number line.
