I just purchased a 871 router trying to connect a small office over a DSL internet connection using IPSec VPN tunnel to the Corporate office Cisco 3000 series VPN concentrator. The VPN tunnel will need to support both voice and data and possible video in the future. I am running CallManager at the Corporate office and there will be Cisco 796x phones at the remote office. I am not sure where to start as far as design and configure the tunnel.
Can someone share their success experience on this type of setup ?
Any documentation on this type of setup is greatly appreciated !!!
But the trick is that you are using QOS at the router, limiting data bandwidth and saving it for voice calls. If you have no QOS at the router, all data packets look the same.
John is downloading 45meg file from the internet. He gets a voice call on his IP phone, sounds like a jumbled. If QOS was inplace, the 45meg download would have been slowed, and the packets prioritized for voice.
I could be preaching to the choir, but just wanted to make sure everyone understands that QOS-less internet is a given, but at least you can keep it clean as it comes and goes from the router with QOS.
I agree 100% with this post. The Internet backbone might not have QoS, but that's because it's a ton of bandwidth. Your connection, whether it's T3, T1, DSL, or Dialup can potentially be a bottleneck. You want to mark the traffic at the endpoint, then configure QoS at the bottleneck point.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
