I have to configure QOS on our catalyst 3560 switches. We have a mix of cisco and polygom ip phones. Can I use the auto qos or not? Are there other things to consider when using cisco and non-cisco voip phones?
How does Polycom tag their RTP traffic? If it tags it with a DSCP of EF like Cisco phones do, then you should be okay to use auto-qos. Though you'd want to use 'mls qos trust dscp' instead of 'mls qos trust device cisco-phone' won't work with the Polycom phone.
