I am at my last rope here with this situation, we have contacted our ISP who does Cisco and they have been unable to create a proper working configuration for what I believe is a rather simple request, they rather refer us to a IBC (Private network) setup...
The situation is as follows;
2 sites both connected to the Internet using ADSL2, they both also have Cisco 877 routers, there is a DVTI IPSEC setup between the sites to route traffic through the Internet.
At each site there is also a phone system, 1 site has the master and the other the slave, the problem is with out QoS when the branch office downloads a file from the main office the main office saturates its upload link (1Mbps) and the call quality drops to almost 0%
So the question is how can we setup the QoS to guarantee as much as 50% of bandwidth will goto the phone system IF it requires?
I can attach the configurations but did not want to clutter up the thread unless requires
