Term	Description
VDN	The virtual directory number (VDN) is a concept on the CTI platform. In the AICC, a tenant corresponds to a VDN after being created and configured. A VDN is equivalent to a tenant or tenant space.
skill queue	A skill queue is a group of agents who can handle problems of the same type or answer questions of the same type. Skill queues can improve the work efficiency of agents and shorten the service duration. Skill queues are classified into the voice, multimedia, video, voice click-to-dial, and video click-to-dial types, which are used to handle different problems. When a user requests a media service, the user's call accesses a skill queue of the media service, and an agent who signs in to the skill queue provides services for the user.
access code	An access code is a customer service hotline provided for customers. Customers can dial an access code to connect to agents.
extension code	To set multiple destination devices for an access code, you can configure extension codes. Assume that the access code is 12345. Extension code 1 is added for routing calls to skill queue A, and extension code 2 to skill queue B. In this way, customers can dial 123451 to directly access skill queue A.
