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.
