We require a database system that can securely hold SIP configurations for VoIP devices. The VoIP devices will be setup to download necessay configurations securely from the database over the internet. A management interface will be required to manage and see the status of the devices. The devices will also be controllable to a certain degree e.g. Reboot. These devices are could be within a LAN or out on a WAN.
This solution will work in a similar way to the Freepbx Endpoint Configuration Manager. It has been suggested that this can be done with MySQL and PHP
