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 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) Post your entire carrier setup, not just pieces of it, and post a single failed call's asterisk CLI. Ask directions if you don't know how.
4) Avoid "X.", it's lazy and leads to problems. Use an extension that accurately describes your calling country AND allows for a dial prefix to identify your carrier so you can add new carriers later.
5) Please use the Vicidial Manager's Manual as referenced above to set up your system for the first time. Beginning to end, don't skip anything. Makes life much simpler (and you often get to keep much more of your hair). When you hit your first pothole, tell us the page and line of the manual and the error you see (precisely) and we'll help you get past it.
