While using ContactPad, agents can control inbound calls using their telephone keypad. This method of controlling calls is called dual-tone multi-frequency signaling (DTMF). Dual-tone multi-frequency signalling sends signals from a telephone keypad to Vonage Contact Center. Vonage Contact Center interprets these signals and controls a call based on the key or keys pressed on the keypad.  A Vonage Contact Center agent can perform similar tasks to the tasks they can perform in ContactPad using their telephone keypad. These tasks include putting a call on hold, consulting with a third party during a call, and transferring a call to another telephone number.
