1) Welcome to the Vicidial 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.

3) DO NOT modify sip.conf. Make all changes according to the Vicidial Managers Manual in the Admin->Carriers and admin->Phones sections to create all sip connections with phones and with VOIP providers.
4) Revert to a "stock" installation. Then Start at the beginning of the managers manual. Do not skip any pages or sections. When you get to the point that all the functions you want are working, stop. If you hit a bump before you get there, bring us the Manual Version, Page, and Line/Paragraph at which you hit your bump and we'll help you past it. This is what the manual is for ... to help newbies get going without each new user re-inventing their system.
