Icon Marratech 6.0.1

Imagine holding meetings and conferencing on the web, face-to-face, on demand, whenever you want and wherever you or your colleagues may be. To be able to talk, see each other and share applications and documents without having to be in the same room, the same building, or even the same country.
And to do all this in a secure environment with no travel time or expense, no conference costs and no fixed meeting room overhead. That's exactly what Marratech will do for you.
Any number of users can join your web conferences and e-meetings by downloading the free client software to their laptops or PCs. All they need is a headset and optional webcam. Your organisation's web conferencing rooms are configured in a licensed Portal which is set up on your company server.
Marratech does much more than bring a video conferencing concept to the web. It will deliver an even more effective work environment than a conventional meeting. To find out how, go to the e-Meeting page, and then see what Marratech will do for your business by choosing Commerce/Industry, Education, Media or Professions.
