we have L3switch->router2800-> satelllite link->router2800, static route is configured and i configured Gre Tunnel on it, but the problem is link has 600ms when no traffic on it, when traffic increases it goes to 1400ms and having huge packet loss, even i can't access another point's router ... what is the common configuration on the tunnel or router, interface to solve this problem? i want 1. voice, 2. mail and other traffic. Looks like for that need QoS, ToS etc, we using non Cisco ip phones so it is not possible kinda.
