What's 'missed call voicemail'?
Enabling your missed call voicemail means you can create a custom greeting that callers will hear when you were busy/unable to answer the phone.
It's a great way of giving a personalised message letting your caller know you've seen they called and will get back to them shortly.
Missed call voicemail goes hand in hand with missed call auto-reply - with both enabled you'll never miss a beat.
