 what the difference between teams call queue and auto attendant

The primary purpose of an auto attendant is to direct a caller to an appropriate person or department based on the caller's input to the 

the calling queue functionalities ..... The following settings shall be configured for customers calling in:

1. A greeting message.

2. Music while people are waiting on hold.

3. Redirecting calls to call agents in mail-enabled distribution lists and security groups.

Auto attendants allow you to set up menu options to route calls based on caller input. Menu options for an auto attendant--such as "For Sales, press 1--For Services press 2"--let an organization provide a series of choices that guide callers to their destination quickly, without relying on a human operator to handle incoming calls.

Call queues are waiting areas for callers. For situations where callers need to reach someone with a particular specialty--such as sales or service--rather than a specific person, you can use call queues to connect callers to the group of agents who can assist them. Callers are put on hold until an agent assigned to the queue is available to take their call.

Used together, auto attendants and call queues can easily route callers to the appropriate person or department in your organization.
