Setup:
Site A Cisco 2911 -- 2 T1 WIC. One going to Site B 1841 another going to Site C 1841.
I am looking for a way to setup a Polycom QOS, judging by several forum posts about this, would it be better to create an access list with the Polycom IPs to limit the bandwidth to 512Kbps? Or if not, could someone send a link for Polycom QOS configs? What is happening is when noone else is using the connection except for the video conference, after about an hour with the T1 not being 100 % utilized, the 2911 GE0/0 interface will start developing input queue errors. What I usually have to do is reboot the router at night and that alleviates the problem since regular data traffic will not cause this problem.
2911 running config:
