qos on vpn tunnel with an asa 5505

[desrochj1]

Hello,

i got a person who connect with vpn on a adsl connection to the corporate network.

this person is using cisco ip phone on his remote location and i did configure

the ASA 5505 to priorize voice over data.

i still get voice skips when the remote pc is uploading data

to the corporate network...what i've done is :

1.with asdm i did create 2 priority queues

  one for inside (queue limit 2048 trans ring limit 512)

  and outside (queue limit 2048 trans limit 256)

2. with the service policy wizard i did create a global

    service policy (all interface) and a traffic class for

    dscp 46 ef and on qos tab i did check the "enable priority for

     this flow"...

3. When using the phone, i clearly see that packets

     are growing on the LLQ queue (show priority-queue statistics)

4. i still get voice skips when uploading data to the

    corporate network... upload bandwidth is about 800k for upload

    the pc and the phone is on the same subnet

got an idea ?

thanks

.

Do you have QoS enabled on both sides of the vpn tunnel?

Here is an example for your reference.

QOS is enabled only on the remote ASA.

the other ASA act likes a vpn concentrator on very high speed link.

only 3 or 4 persons have voice skips over about 30 persons.

Source of voice skips is always on remote location.
