port speed to 100 Mbit/s and observe QoS lost packet alarms, then review
your Ethernet port speed settings.
With the port speed at 10 Mbit/s it is particularly important to set the voice
QoS on the reciter port of your site router or switch to a strict priority queue
policy - which is the same policy that you should also be setting for your
site link ports. The default QoS settings restrict the voice bandwidth to 1/
25th of the port speed which is smaller than the required bandwidth for
typical systems at 10 Mbit/s.
