Scalable VoIP Cluster with custom billing engine and customer front-end

We carry minutes between mobile operators and wholesale voice companies.

We have so far done development of our platform in house.

We are looking for someone to design / redesign several components:

- An OpenSer/Sips front-end that functions much like a border gateway controller to back-end Asterisk. Some calls are SIP-to-SIP, some are SIP to IAX2 (or IAX2 to SIP (or even IAX2 to IAX2)). 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

Run every 5 minutes to rate calls based on asterisk cdr records

Redesign DB design for HA, failover etc.

Billing based on different interval, PDF invoice generation, supplier billing reconciliation.

- A Web Portal written in the Zend Framework with extensive YUI / Web 2.0 functionality comprising of several components:

MyRates - inhouse application to manage rates from supplier, collate and offers to customers. Speadsheet import and generation.

MyAccount - front-end to see usage bank statement like usage

MyCDRs - CDR front-end application integrated with Google Apps

MyStatistics - front-end to view individual customer statistics (also contains back-end offline calculation software)

MySwitch - module containing information based on Nagios about asterisk switches at customer sites

Redesign / updating of the web components required

Additional integration with Nagios / Cacti / Mrtg might be required.

Current system is based on Asterisk / PHP / MySQL

Solution must scale to 10s of millions of minutes per month. Much of the solution runs on FreeBSD, some on Linux.

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.

Full project cycle required, design, implementation, testing, documentation etc.

Good communication skills and proven ability in the different areas required.

Taidot: PHP
