Good afternoon. My area of activities associated only with asterisk. Have extensive experience in installing and configuring Asterisk. I will be glad to help you realize your goals. This is a very interesting project for me. Asterisk works fine on the VDS servers.
But I do not recommend to install FreePBX and asterisk to use on config files, as FreePBX limits the ability to integrate asterisk into other CRM system and weight system. If You need to control asterisk using the web, you can provide a different mechanism.
Will answer any of your questions.
With respect. Igor
