Our Customer have a solution of Video Conference that is presenting the following problem: When a one conference is starting between 02 sites (endpoint)without the MCU 3450 is work. When put MCU3450 for connect 03 sites the presenting work by any minutes and the screen stop and start again after reset the system. We did the test isolated configuring only LAN, but the problem continue. Somebody have any idea of that is occuring? I don't know the MCU, but, appear the configuration is ease.
