Over the past 20+ years i have mastered the art of Asterisk Ninjitsu. When choosing me you can expect that job will be done quickly and perfect. Highly trained with any Asterisk distributions. PBX and non Asterisk PBX (Issabel PBX, asteriskNOW, TrixBox, Elastix, PIAF, freePBX, MirtaPBX, and 3CX) A2Billing Predictive dialers (GoAutodial and ViCidial) Multitenant PBX Thirdlane and VitalPBX and Hardware based PBX (SwitchVOX, Yeastar myPBX and Grandstream UCM). Class 4 and 5 Softswitches ( Sippysoft, Porta One, VOS3000, Voipswitch, Mediacore, Nextone)
I have a solid experience in designing, installation, configuration, deployment and troubleshooting VoIP hardware and software applications.
I am currently doing full time consultancy service for companies both local and abroad and already have at least a total of 600+ PBX server deployments.
I don't like to do something that doesn't need to be done, so i usually prefer to use available developed components and solutions. But when something is needed and not available, as an experienced shinobi, I execute the techniques of asterisk programming and scripting.
My rate maybe higher than others but i can assure you that I can deliver any work satisfaction guaranteed!
