handle support queues?

I'm looking for something like the FastPath plugin in openfire.
From the FastPath readme:
The Fastpath plugin adds support for managed queued chat requests, such as a support team might use. For example, a web based "Live Support" interface can point a potential customer at a workgroup representing the Sales team. Members of that workgroup will receive notification that a someone is waiting and when someone from that workgroup accepts, the customer and the team member will be connected to communicate with each other.

Is there a similar functionality in ejabberd?
If I should develop a custom module, what module could be the best reference?

Thanks
