Check duplicate numbers in contact module in suiteCRM

Hi Every one ,

I have created 2 more phone number input boxes in contact module ,So I need to check duplicate number which means system should not allow duplicate numbers .

For instance ,I have fields called Mobile,whatsAppNumber,SecondNo if I create a contact like mobile number: 1234 ,whatsAppNumber:5678 and SecondNo:0987

if I create again one more contact with this number system should not take either if i give whatsAppNumber: 1234 should not take .

Could any one help on it please ?
