Description (partial)

In CWMS 1.1 and 1.5 we observed audio quality issues (robotic audio, chopped voice) introduced by CWMS server. 
 When the issue happens, in the gyromain_info logs, we identified the slowness in processing packets and increasing drop rate like in the example below:
 [09/03/2013 13:31:56.436 pid=12392 tid=-328299632] Warning:[chn=  76,conf=998]Chn QoS:dropRate=9,slowProcessing, qosCode=0x14
13:32:58.476 pid=12392 tid=-191931504] Warning:[chn=  76,conf=998]Chn QoS:dropRate=6,slowProcessing, qosCode=0x14

CWMS 1.1 MR3 or 1.5
