Hi, i have a phone thats no working fine, it unregister all the time from the sip server.
The port connected to the phone has output queues dropped on queue 1. ¿That's normal? ¿What could be the cause that there drop packet?
Thanks!
I have this configuration for Qos on the switch port:
interface FastEthernet0/15
switchport mode access
switchport voice vlan 15
priority-queue out
mls qos trust cos
spanning-tree portfast
sh mls qos int fa0/15 st
FastEthernet0/15 (All statistics are in packets)

Ok, i have a doubt about this: Why if QoS drop packets, why don't loses any ICMP packet at the same time?
in which QoS queue belong the ICMP packets?
Thanks.
