Simplest way to limit bandwidth for internet browsing to preserve for VOIP traffic

Here's my situation.  We recently went live with a hosted VOIP system (CallTower hosted Cisco UC). We are relocating our office in a few months so we decided not to put in a dedicated circuit for voice and instead use our 20 meg DIA connection. 

We have a PA-200, my guess is about 20 to 30 users max using the internet concurrently and same with phones. 

We have a Cisco ASA 5505 that is bypassing the PA-200 and making a direct VPN connection to CallTower and carrying the voice traffic.  Since the PA-200 is not directly connected to the ASA - I don't think I can take advantage of the QOS policies for the VOIP traffic; however, I would like to put a limit on the amount of bandwidth used for Internet browsing/uploads and downloads, so that our bandwidth doesn't get maxed out if someone decides to download a large file and compromise the VOIP quality.   

Is there an easy way to use the QOS profile/policy to limit internet traffic (ingress/egress) for an IP address range so we can preserve enough bandwidth for the ASA to use to carry the VOIP traffic? 

 

Thanks for any advice.

Yes you can configure QOS policies for a subnet or ip addresses.

 

Step 1 Configure QOS profile

Step 2 QOS policy

 

Specify the traffic on which you have to apply  the QOS

Step 3 Appy the QOS:

 

Main task is while applying the QOS: In this example ethernet1/2 is LAN interface and ethernet1/1 is WAN interface

For downloading apply the QOS on ethernet1/2 and for upload apply the QOS on ethernet1/1

 

Refer to the docs:
