1) Welcome to the Party!

2) As you are obviously new here, I have some suggestions to help us all help you:
When you post, please post your entire configuration including (but not limited to) your installation method (7.X.X?) and vicidial version with build (VERSION: 2.X-XXXx ... 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 "manual/from scratch" you must post your operating system with version (and the .iso version from which you installed your original operating system) plus a link to the installation instructions you used. 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 used the word "Keen". Kudos.

4) Are these 200 agents all in one campaign or in various different campaigns?
5) If you have any campaigns with more than 30 agents, look in the Manager's Manual for the "Adapt" dial methods. This is a difficult-to-grasp system, but once you gain some experience, it can drop your wait time to ... well, nothing, if you have 50+ agents in one campaign ... without exceeding the 3% cap on Drop Calls. DO NOT go to lunch after setting the system to any of the adapt settings.
6) Are all these agents READY / INCALL or or 40% of the Paused at any given moment in time?
