There is no vicidial 2.0. But there is a goatuodial 2.0 and a vicidial 2.0.4, vicidial 2.0.5 and vicidial 2.2.0 and vicidial 2.2.1 and vicidial 2.4 and vicidial 2.6. So please try to figure out what you actually have, it helps if you actually copy it from your screen (no memory involved).
I would strongly suggest you read the Vicidial Manager's Manual which covers all sorts of topics (such as inbound and outbound calls ...). In your case, you appear to be in need of the Inbound ... but instead of trying to skip directly to it, I would suggest you make sure you have not skipped anything before inbound. Carrier setup is very important for inbound as well. It is safest to start at page one in the manual and perform all the tutorials until everything you want works, then stop. If you skip something, it invariably turns out to be something needed for what you want ... and you have to go back several times until you find the one thing you missed. LOL
You will need to configure your carrier to have "context=trunkinbound" in the "account entry" field. You'll also need to configure an Ingroup, and select all the agents who you want to have permission to get these calls. You'll then need to configure a DID and point it to this ingroup. And finally, you'll need to modify the campaign to accept inbound and then select this new inbound group to be allowed. Much more detail in the Manual, though
Oh! newbie suggestions! almost forgot:
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.
