    Speed and quality are my second and third names Escrow on start, released upon completion, no exceptions! I don't stop until your project is done. I don't want to be involved in projects promoting porn, aggressive marketing, spamming, etc! I've lost count of the number of VoIP/Linux/Cisco installs and upgrades and modifications I've carried out. I'm also a developer member of various VoIP projects so I'm able to offer much more value and choice in all areas of VoIP eg. custom Asterisk modules, modifying Openser(Kamailio) or Asterisk's source code to make custom features, etc. I am not one of the many bidders who bid for everything with a generic sales pitch. I specialize in VoiP/Cisco/Linux only and do not work with anything else. I also support all my work for 6 months after completion in case of upgrades etc. for a low price.
