I have extensive experience in VoIP engineering, support and management. I have experience in all aspects of VoIP including billing including Text, SMS, Voice, Domestic and International traffic, most open source systems including Asterisk & Opensips. I've personally used soft switches as well as major OSS and BSS systems. I have extensive experience in Domestic(US) routing, billing & LCR including LERG, INTER/INTRA, RBOC/NONRBOC, Reporting etc. Same goes for International traffic. I built a VoIP billing system from scratch using PHP/MySQL.
