Q. Why does the bandwidth sent from the Codian MCU to my endpoint drop?
A. In H.323 calls each end controls the bandwidth sent to it. Therefore the bandwidth sent to the endpoint is controlled by the endpoint itself.
Endpoints will reduce the bandwidth because they are seeing packet loss. To stop the endpoint doing this you need to check the network settings. Some endpoints also allow you to stop the reduction of bandwidth even when they are seeing packet loss. For example, on MXPs you can open a telnet session and type "pldownspeed off".
