Wifi Calling Static issues

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Initiate Wifi call from RT-N56U running 3.4.3.9-095 firmware
2.
3.

What is the expected output? What do you see instead?
Expected output would be clear voice on both ends of the call. Outbound voice 
is affected, inbound voice is completely clear.


What version of the product are you using? On what operating system?
3.4.3.9-095 firmware, RT-N56U ASUS router. Android OS 5.1.1, Samsung Galaxy S6 
(Sprint)


Please describe the problem as detailed as it's possible.
The reason I suspect the router/firmware is that Wifi calling has been fine 
from my Android S6 device on other Wifi networks, even those with much lower 
bandwidth (my connection consistently tests out at 30Mbps down/5Mbps with 0% 
packet loss). While the S6 device is connected to the RT-N56U running 
3.4.3.9-095 firmware, callers complain of static which points to potential 
issues with outbound call bandwidth/QoS through the RT-N56U router. Inbound 
voice quality is perfectly fine. Again, because this device has worked 
perfectly fine on other (slower) Wifi networks, the router is most likely the 
culprit.
