Scalable multi-servers, load balancing, HA required. Must have LCR component based on custom MyRates system.
- A rating engine based on custom PHP software and Mysql

Redesign / updating of the web components required
Additional integration with Nagios / Cacti / Mrtg might be required.
Current system is based on Asterisk / PHP / MySQL

This is a highly complex solution with millions of minutes currently being switched requiring a bona-fide expert in the technologies and with extensive VoIP/Asterisk/Billing/Web 2.0 experience.
It will be necessary to understand current software to understand scope of project.
