I have a working installation of Asterisk 1.8 on Cloud server with Centos 5.6, with Freepbx 2.9, Webmin and A2billing last version.
My plan is to sell bundle packages (no calling cards), so I need some customizations, like A2billing integrations with [url removed, login to view] Gateway, integration with features from freepbx like follow me, IVR and editions of Voicemail, etc.
Eventually I want to install Wordpress for ease the design part, but I would like to integrate with a2billing too with just one login.
Additionally, I need a Fax solution integrated, it could be Hylafax, but need the interface to allow customer to login like web to Fax, and fax to email. A2billing again handling the billing part for the FAX feature.
Also, some recommendations to harden the Asterisk server.
I have my Voip provider who has an API to use for some features.
If you have samples already working online, please, let me see or test a demo of those projects.
I am web designer and know HTML and basic PHP, so I can do the design customization. I'm in Need to expand my services into the VOIP area, so looking for an advise and assistance.
Let me know to discuss details.
