ACD is often used in offices for customer service, such as call center. The ACD system
handles the large volumes of incoming calls from callers who have no need to talk to a
specific person but who require assistance from any of multiple persons at the earliest
opportunity. ACD on the SIP-T20P/SIP-T20 IP phone allows the ACD system to distribute
large volumes of incoming calls to the registered ACD users. To use this feature, you
