In simple words IVR gives your company a professional look. eg. when someone calls you at your company phone he will hear a greeting “Thanks for calling ABC Insurance. We deal in Home, Auto, RV and Personal Insurance too. Please ask for a 10% discount from one of our representative. For Sales Department Press 1, for Accounts Department Press 2, for Operator Press 0”.
This is as simple as that. It really gives your company a professional million dollar look. To add more to it, when a caller in waiting on the line to talk to the next representative he can hear to your promotions. A great upselling feature!
