No its not call waiting that i am sure about. Its like a constant beep with a difference of 2-4 sec between each beep throughout my calls and it started happening a frw months ago.
The Genius Bar is the area in the Apple Store where you can get free support from Apple Techs.
You can try that, but be sure you make a backup before you do as it erases all settings and information:
Restore your iPhone, iPad, or iPod to factory settings - Apple Support
You get beeps when another call comes through and you are on the line. Are you sure that's not "call waiting"? If that's it, and you take the phone away from your ear you should see the notification.
You probably should make a free Genius Bar appointment and have them check it out, if you can get it to happen while there. Are you able to narrow down the calls it happens on?
Whats a genius bar? i noticed it intentionally if this happens during every call or a few specific ones n yea it happens only during specific calls ...
Thank you n one last question. I read on internet that doing a factory reset might solve it. Is it true?
Thanx heaps !
You're welcome. Good luck.
