ASA 5505 PIX 515e QoS issue
Hi Experts,
I have a Cisco PIX 515E at our main site and we are using an ASA 5505 at our telecommuters site. I have set it so that VPN works fine and our user can access internal network, files, email etc. We use 7941 IP phones from Cisco, which is also working for our user. The issue I am having is that for every 3rd or 4th call the quality of the call deteriorates. Is there a way to set up QoS on the ASA so that call quality does not deteriorate? On the PIX I have version 7.0. ASA version is 7.2(3).
Thanks

We use Cisco Call Manager 4.2, if that helps. I will try to find out and send you the info. Thanks once again.

Would this give the port numbers, I got it from the Call Manager:
Ethernet Phone Port - 2000
Digital Port - 2001
Analog Port - 2002
MGCP Listen Port - 2427
MGCP Keep-alive Port - 2428
Ethernet Phone Port - 2000
Digital Port - 2001
Analog Port - 2002
MGCP Listen Port - 2427
MGCP Keep-alive Port - 2428

Would the following work instead of the port number?
priority-queue outside
class-map Voice
match dscp ef
policy-map Voicepolicy
class Voice
priority
service-policy Voicepolicy interface outside
Thanks.

Hi raptorjb007 I have applied the voicepolicy and the priority is being assigned correctly as shown below but there are still issues with quality. The other person cannot hear my user sometimes. Are there some commands I can run to see status on the call?
Priority-Queue Statistics interface outside
Queue Type = BE
Tail Drops = 0
Reset Drops = 0
Packets Transmit = 8052
Packets Enqueued = 0
Current Q Length = 0
Max Q Length = 0
Queue Type = LLQ
Tail Drops = 0
Reset Drops = 0
Packets Transmit = 44119
Packets Enqueued = 0
Current Q Length = 0
Max Q Length = 0
Priority-Queue Statistics interface outside
Queue Type = BE
Tail Drops = 0
Reset Drops = 0
Packets Transmit = 8052
Packets Enqueued = 0
Current Q Length = 0
Max Q Length = 0
Queue Type = LLQ
Tail Drops = 0
Reset Drops = 0
Packets Transmit = 44119
Packets Enqueued = 0
Current Q Length = 0

Ok. I will check that. Currently our flow from end to end is ASA at client - Border Router - PIX - Switch. On the Border Router I have a policy which is like
policy-map VPN_POLICY
class IPSEC_class
priority percent 20
class class-default
fair-queue
Will this need to be modified in order to honor the policy on the ASA as only 20% of VPN traffic has priority? Thanks.
policy-map VPN_POLICY
class IPSEC_class
priority percent 20
class class-default
fair-queue

Any luck?

No nothing much has changed. We still have QoS issues on the calls. We applied QoS on the ASA, Border Router and PIX. We are going to keep testing it out for some time. Thanks for all your help.

1. How can I find out which port to use for voice? Is this determined on the PIX?
2. Based on the above code I do not need to apply anything on the PIX correct?
Thanks.
