I'm trying to diagnose occasionally sketchy VoIP quality in a medium sized network running Cisco switches, Fortigate firewalls and RingCentral softphones (no actual hard phones anywhere).
I took a look at a Wireshark capture on my laptop going to RingCentral during a call. It doesn't look like DSCP is set on these packets. This tells me that all of the QoS on all of the switches is actually doing nothing at all. Am I reading into this correctly?
