10+ years Linux / VoIP / Asterisk experience. I have hands on experience with VoIP FXO/FXS equipment like Cisco (ex Linksys), Polycom, Grandstream, 2N etc. I have vast programming skills in Linux bash, PHP, especially Asterisk agi scripting, AMI command scripting using PHP sockets and Freeswitch Lua scripting. Also, I made a few FreePBX modules from scratch, and I have completed few A2Billing projects with significant inbound IVR changes . Looking through my project at freelancer.com you will find some Vicidial projects as well Kamailio and Opensips project I completed for some companies that doesn't exists anymore, so I can say I'm mid level expert (Kamailio especially). Vitualization with ESX I tried but I have hands on experience with Workstation 10 (primarily from console, but I can use GUI as well) PRI & PSTN card installation I did many times before 2011. (I have "To Whom It May Concern" letter from a Serbian company) since we use direct SIP trunking to Telekom from that time.
