1) Welcome to the Party!
2) 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) I know of no such feature in Vicidial.
4) However, it would be possible to write a custom agi script to check against today's calls and make such a transfer. If it were added to the DID scripts, and a value placed in the DID module, it would even be possible to make it a variable value for the call count and change the call route based on a comparison to that value. Which means any DID could have a setting to re-route a call to a secondary location based on a daily call limit per callerid.
For you, it would mean putting them on permanent hold until they hit 10 calls, at the 10th call they would transfer to the "Real" Ingroup instead.
For others, it could mean something like sending the caller to a Management Queue if they exceed 3 inbound calls in one day instead of the regular queue.
Interesting feature request.
