Call transfer allows you to transfer a call from your line to the appropriate person without losing the caller. This allows you to get your customer where they need to go without forcing them back to a main menu. You can also transfer outside of your company or to any external number.
This feature is beneficial when a secretary has transferred a call to you but it turns out the call needs to be pushed somewhere else. Simply transfer them directly to the correct department or individual. Do you have a number of folks calling in asking for a different business with a similar number? Simply set up another (free) extension that forwards to that company’s number.
