I used to be using the analogue phone calls but
recently got a Singtel bundle deal for optic fibre and changed my
phone line to digital phone call to enjoy the free calling. I've
also subscribed to caller ID all along and it used to be working
fine until I changed to the digital call. The caller ID which
appears on my phone every time I receive a call now comes in weird
characters which cannot be read instead of phone numbers. Any
solutions to this?
