As i have mentioned that sound "your call is being recorded" as drawback but you have said that "it's due to the privacy issue" but most of the peoples work based on their mobile and calls only ,so we must record our calls for our future reference,every time When we make a call or attend a call we hear that noise "your call is being recorded" that makes us feel annoying even sometimes irritating and makes our work frustrating. Atleast provide as a option to turn off it manually
