Over 8 years of working experience as Linux and VoIP system administrator. Over the years I have been part of a team or a lead system administrator in-charge of implementing opensource voip solutions. I had deployed pure Asterisk, AstersikNOW, Trixbox, Elastix, PBX in a Flash, but my personal choice is FreePBX in which I am an expert. I am sorry, but I can not send the link from LinkedIn to my public profile as it has been prohibited by ToS. If you want more information regarding my projects and my expertise look at my LinkedIn profile.
