Easy setup, good voice quality, terrible QoS
Reviewed by George Lohrey on 9/29/09
The voice quality is very good with no echo. The QoS does not work. The uplink and downlink bandwidth settings seem to be reversed and setting the bandwidth to 10M slows the WAN to about 2M, and don’t even try anything lower it is unusable. On top of that it does not even prioritize the voice traffic. Having to reboot for changes to take affect is also a pain.
