[AFMUG] ePMP VoIP QoS

[George Skorup]

Yo Cambium, you need to add DSCP 12 (Assured Forwarding) in addition to 
DSCP 46 (Expedited Forwarding) to the default VoIP priority 
configuration. We're finding more devices sending SIP packets as AF and 
RTP as EF. AF isn't prioritized and out-of-band signaling (prompts, etc) 
are sent as SIP messages so sometimes these are getting dropped, not to 
mention registrations, invites, etc. And more devices are stupid (mostly 
Grandstream), they only let you set ONE priority value for the entire 
device. These are coming default as DSCP12/AF. I've tried to get 
everyone to change this to 46, but they don't remember.

Or just apply the whole Canopy DiffServ table. We've never had to change 
any of those code points. Turn HP on, it just works.
