Automatic Call Distribution (ACD)
ACD is often used in offices for customer service, such as call center. The ACD system handles
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 all IP
phone allows the ACD system to distribute large volumes of incoming calls to the registered
ACD users. To use this feature, you should configure an ACD key in advance. For more
information on ACD key icon indicators, refer to Status Indicators.
Note
ACD is not available by default. Check with your system administrator to find out if this feature is
available on your phone.
Multicast RTP is one way only from the sender to the multicast address(es) (receiver). For
outgoing RTP multicasts, all other existing calls on the phone will be placed on hold.
