1) Welcome to the Party!
(although with 26 posts, you've apparently been here a while ...)
2) In case you have forgotten, here are the newbie suggestions:
when you post, please post your entire configuration including (but not limited to) your installation method and vicidial version with build.
this IS a requirement for posting along with reading the stickies (at the top of each forum) and the manager's manual (available on EFLO.net, both free and paid versions)
You should also post: Asterisk version, telephony hardware (model number is helpful here), cluster information if you have one, and whether any other software is installed in the box. If your installation method is "from scratch" you must post your operating system and should also post the .iso version from which you installed your original operating system. If your installation is "Hosted" list the site name of the host.
If this is a "Cloud" or "Virtual" server, please note the technology involved along with the version of that techology (ie: VMware Server Version 2.0.2). If it is not, merely stating the Motherboard model # and CPU would be helpful.
Similar to This:
Vicibox X.X from .iso | Vicidial X.X.X-XXX Build XXXXXX-XXXX | Asterisk X.X.X | Single Server | No Digium/Sangoma Hardware | No Extra Software After Installation | Intel DG35EC | Core2Quad Q6600
3) You did not mention your Vicidial Version, but later versions have a system called Quality Control in them which allow selecting specific Dispositions for QC management. Then the QC agent (with QC permissions) would log in and go to the QC menu and walk down the list of QC marked leads. Redispositioning them from "SALE" (or whichever dispos you chose for QC management) to QCSALE or QCFAIL or QCCANCEL. If QCFAIL is chosen, the lead is immediately sent back to the original agent as a Callback to allow that agent to re-call and re-sell. The QC agent can also push a button to call the client during the QC process.
But as I said, you don't mention your version ... If you don't have it, you can just upgrade to get it. To test, you can activate the QC functions in system settings and then change your user to have QC permissions. If you get a QC Menu (on the left side) at that point, you're on. If not, upgrade.
Happy Hunting.
