Hey,
i have one question!
i established VPN between 2 sites allowing VOIP thru the tunnel
my internet speed is 4Mbps
i want to give priority for VOIP and E-mail (SMTP,POP3) during congestion while dropping other packets
does my Configuration fit my scenario ? does this mean when congestion occur, priority traffic while transmit First ??
Thanks

I think the ACL for voip traffic should include both directions, so you sould add reverse entries.
Or, wich looks better to me, you can match voip traffic in the class map using dscp bit. Smth like this:
class-map VOIP
match dscp ef
For email-related traffic it's ok.

Plus, cause priority queuing works only in outbound direction, you should apply (at least for voin) the policy map on both interfaces, or globaly.

thx
actually i applied the QoS in the outside (outbound) direction
so i guess everything is working fine
Thanks =)
