Marratech v6.1 is available for Windows, Linux and Mac OS X. Marratech v6.1 includes major changes to the voice and video code. Please read the release notes carefully.
- Marratech v6.1 can co-exist with 6.0 users in the same meeting room.
- Marratech v6.1 includes the ability to remove echo and feedback. This requires more CPU and memory and may be turned off if you have a headset.
NOTE
Marratech v6.1 will run under Mac OS X v10.3.9 but has undergone very limited testing and is therefore unsupported. There are a number of issues fixed in Mac OS X v10.4 Tiger that improve Marratech performance. No separate download required.
