I am running small business. Set up Extention 1 for Sales, 2 for Support and 3 for Emergency. When customer called, I manually save, but it is not linking all extension no. For example, customer called Extention 1...I save it manually their contact. However, if they called Extension 2 next time, it is not linking customer data. So, I don't know who is calling. And I have to save contact manually again for Extension 2 customer database. So, I highly request to customer data is linking all extention no. I hope you understand my problem.
