This is the QoS i have configured on the router to give priority for VoIP
My VoiP subnet is 172.20.92.0/25
This is the following QoS i have
class-map match-all voice
match access-group name voice
match ip dscp ef
ip access-list extended VOICE
permit udp 172.20.92.0 0.0.0.127 any range 16384 32767
I do not see any packets that match the voice policy nor the access-list.
Is there any change required in the access-list?
Yeah you could mark the traffic ingress to the router and then just match dscp and prioritise egress over the WAN.
What kind of switch do you have? Its most likely that if its not configured to trust the IP phones, it will by default strip the markings of anything it receives.
