Architecture:

Hub and Spoke, Site to Site Ipsec VPN tunnel

HQ Site:

ASA5520

Call Manager

Cisco IP Phones

Remote:

PA5020

No Call Manager

Cisco IP Phones

Remote users connect to HQ via VPN tunnel between ASA and PA

QOS Policy

src.zone Inside dst.zone Inside to match traffic over the tunnel

apps

rtcp, rtp and sccp

This is working pretty well. Any further advice is welcome.

Make sure you have prioritize all apps use by the phones. You can run a report for src=IP of a phone and review all the apps/traffic generated by the phone. If there's any unknown traffic from the phone, you may want to classify the unknown and add it to the QoS policy. Thanks.

Also dont forget to prioritize in both directions.

If I recall correctly the QoS is always setup on the outbound (egress) interface.
