RMX ISDN Audio Issue

Hi there,


On Multiple ISDN devices I am experiencing an Audio disturbance when making an ISDN Video Call.


A call over ISDN for example 128kbps is established and the call is connected with Audio and Video and no Errors on the Call. A strange sound is coming through that can be closest described as crickets chirping.


When an Audio call is made over the same ISDN line then the Audio is clean.


I have tested this with 3 different RMX Devices from 3 different regions on version, 8.1.3, 8.2.1, and 8.5.


It seems to be an RMX issue and want to know how I can resolve this problem.


Please advise?
