Audio Output Garbled in Downlink


I am working on Channel Codecs (L1-DSP). I am facing some problems while testing with the lilve n/ws in India (Hutch n/w) In the DTX mode, I hear some waterfall kind of sound in the background. This is happening only in the downlink. However the call stays connected. I am unable to figure out the problem.

Awaiting ur responses.. If this is not the right group to post technical stuff on wireless telecom, pls let me know the correct group

Thanks Sandeep
