Avaya phone and Cisco 4507R+E

Need to know if I need to enable QOS on the swithcport that the phone is connected to or can I just use the MLS command?

This is the Video Over IP forum, you might want to move this thread to some other community.

It depends, if your Avaya phone uses DSCP settings for things like SIP signalling and RTP (af41 and or ef).

You can simply put a trust statement on your access port and pass it on.

Thanks for the reply. I only see the command qos trust extend cos 0-7? Not sure if this will help

[Dennis Mink]

sure does, If you set the access port to trust these IP presedence values, then you have to make absolutely sure that your phone sends the correct cos values.
