Call Queues
With WebFones call queues make it easy to create your own Call Center! Use queues to distribute incoming calls between representatives. Representative's phones ring, regardless of physical location, according to the ring strategies you specify. Call distribution options include: simultaneous ring; in-series; round robin; least recent; fewest calls; and random. You can also set WebFones to play a custom informational message about your organization or music while callers are waiting.

The Call Queues option places unanswered calls in a queue and plays music on-hold until calls are answered. Call Queues are different from Extensions in that they play Music on Hold while the user is waiting for someone to pickup the call. They also have a lot more options for ringing phones.
