    VoiP

    Spain - Last active: 1 month ago - Tests: 1 - Portfolio: 1

    Hi, I´m a telecom entrepreneur and active in VoiP/SIP on a global scale. Since 1996 i`m into IT and have a broad knowledge of many techniques. Because of my global understanding i do not need to know every detail to be able to provide the best solutions. Im a strong conceptual thinker, I have an extensive network of experts available (i use them myself). So if u have a problem or project, i can have that arranged for you. Me and my team do anything telecom or VoiP, we are experts in Hosted VoiP and SIP troubleshooting. But we can help u with anything u may need, including development of apps, websites and IT problem solution. We are managing three Kazoo clusters and developing whapps for them. I am very busy, but its nice to have other projects in the course of a year next to your own. They keep you sharp, takes your mind of your specific tasks and are fun, most of the time.
