Hi Sabrina, 

now the log attached. 
What i found out: 

error: 2016-09-07 11:14:22:770 QOSAddSocketToFlow failed to add a flow with 
error 87 appears several times. 
What does that mean ? Is it severe ? 


Is the following interesting ?

What is "frozen list" ?


        RTP  audio=[d= 80,0,u= 79,9], video=[d= 65,5,u=1541,4], text=[d=  
0,0,u=  0,0] kbits/sec

appears often. Video d (downstream ?) is mostly between 60 - 70 (Kbit/s ?).
That's the problem, isn't it ? What's the reason ?
