Lets say i am calling Pepsi Co for example, i use the caller through pipedrive to dial out to Pepsi.Co. , when Pepsi answers its an automated system that requires me to input a contacts first or last name to search for their extension. I am unable to input the persons last or first name through the caller as there are no letters to know which digits to hit to get the appropriate last or first name inputted. 


I hope this helps , ultimately , open up your own cellphone and go to where you would be dialing out a new #. Do you notice the numbers have the alphabet on them ?
