The wait-queue function informs callers of their position in line while waiting for an agent. And the custom-greetings feature allows you to advertise new products or share announcements with clients who are on hold or queuing.

For a VoIP system to work, it needs a means of routing calls between users or to the outside world. In a cloud-based system, this gets handled by a virtual PBX. In the cloud, this routing is managed by your VoIP provider, which is part of why you're paying them. Whatever vendor is supplying that is also running a large PBX operation in a data center somewhere, and slicing off a little of it to dedicate to your organization in exchange for your subscription fees.
The auto attendant feature automatically redirects an incoming call to an extension without the need of a telephone operator, while audio conferencing lets multiple users join a single call. With ring groups, you can share the distribution of incoming calls among group members. As one of the best virtual phone service solutions, VirtualPBX provides ACD queues, an advanced version of ring groups, among its features. Given that it distributes calls to a group of users, this functionality makes managing a call center with large volumes of inbound calls much easier.
