ASTPP customisation

We require ASTPP customization. - Resellers need to be able to create their own invoice and warning templates. These templates are stored in the database. Currently ASTPP uses global templates. - We'll need to be able to create openSIPs/FreesSWITCH profile aliases so that we don't need to create a SIP profile for each client. This will allow a reseller to have a custom URL displayed. If the reseller can upload their own logo it would be even better. - Both clients and resellers need to be able to see see origination rates. These rates will need to reflect the rates that the reseller or administrator specifies. For example an administrator will import rates and add a 5% markup for resellers. The origination rates with a 5% increase will need to be displayed when the reseller views their origination rates. The same will apply to clients. Note that OpenSIPS is used as a FreeSWITCH proxy and there is a dedicated database server. All the servers are part of a fail-over pair.
