Hi Please help me on this:
How to configure QoS for Video Conferencing . which parameters I should follow for this.
Installed VC Device like this VC Device àCore Switch [Native VLAN]àFirewall [5505 ASA]àCisco Router[2900]àISP
NAT=192.168.X.X to 125.X.X.X in Firwall
Should I configure QoS into all Network Device [Switch+Firewall+Router]
I have configure QoS like this as below:
lass-map match-all VC_Traffic
match dscp ef
match dscp af31
match dscp af41
!
policy-map Outbond_Policy
class VC_Traffic
priority percent 20

Hi,
You need to apply QoS on different devices. Please refer following hyperlink for the same.

A FW and NAT, eh? Are you running across the Internet? If so, is link also used for "generic" Internet access? If first, often shaping is needed if two sides have different bandwidth connections to the Internet. If also the second, unless you can enable QoS on ISP egress toward you, you cannot effectively manage ingress.

I joseph when I bypassed firewall then VC is working fine no packet drop. But when Firewall is working in between VC and router then packet drop.
That’s mean Firewall[ASA 5505] Drop VC packet.
125.19.X.X is VC ip which is NAT with private IP
access-list outside_acl extended permit icmp any host 125.19.X.X
access-list outside_acl extended permit tcp any host 125.19.X.X eq ftp
