[cisco-voip] Poor Receiving Audio on 69xx, CUCM 8.5.1

[Roger Wiklund]

Do you have QoS enabled on the switchports where the 6921 phones are
connected? I would check the network to ensure you have the EF tags
and QoS is enabled end to end.
I know you said that the other phones are working, but I would check
for EF drops in routers/switches.
