We realize that some of our users are new to Linux, and that Asterisk is the only reason you are working with Linux at all. Many long-time Windows admins have never used (or wanted to use) a command line and find the provided instructions frustrating and/or confusing.
The problem is that we offer a very technical product (with deep integration into Asterisk and the operating system, etc), requiring a level of Linux expertise that some admins don't have. If we offered detailed explanations for each Linux command, networking concept, operating system parameter, etc. our installation guide would be huge. Sadly this is not an option for us.
If you are a commercial user we recommend purchasing installation assistance allowing our professional services group to perform the installation for/with you. We can offer a turnkey solution (from design through implementation) or just step in where you need help.
If you are a home user you may be better off using a 'built-in' option provided by one of the many configuration generators out there. You will be losing a substantial number of features and capabilities, but at least you can install a 'built-in' option by clicking BUY/INSTALL on a GUI. Please note that HAAst, SecAst, and SecData are targeted at large and critical commercial call centers - not home office / small office environments (Telium products are on a different scale than 'built-in' products/modules). You are welcome to use Telium products in home office / small office environments but realize that it's like using an 18-wheel truck instead of a bicycle. As a home user the bicycle may be a better fit.
