Cisco 870 series with Polycom video cam

I have a Cisco 871 DSL router with the following configuration section that puzzles me.  I have a Polycom VSX6000 camera connected via a public static IP.  

Here's the problem...some days I can use the Video conference without any issues. Like this morning I made several video calls then at 1:00PM I initiated a call. It went through then seconds later it was disconnected and I have yet to get reconnected.

This is part of the router config. I'm thinking it's something with the router but it could be something with the camera. Need help fast because the boss needs to make call first thing Monday and I'm totally stumped. My vendor can't help because he has never seen this behavior either.

How about the port flow settings on the router or switch. We have to have ours set at 100 Full Duplex and not Auto for our Polycom units to work decently. Otherwise we get choppy video.

Randy,
Thanks for your response, I have already taken care of the speed settings on both devices.

Just to let you know I spent 10 Hours working this issue out Friday afternoon. I had a conference call with the vendor who sold us the equipment, Polycom, and eventually Cisco.  I went through 3 different Cisco engineers.  We finally got to the bottom of the issue. My predecessor (IT), who assigned the IP for the Polycom assigned the same number as the Proxim wireless access point that we use on our system.

Interestingly, neither the Polycom or any other device on my network complained of an IP conflict.  So when I got a call through it was a fluke then when we tried it again it couldn't see the device.  Go figure!

Sorry but I really can't give the points I'm just going to close the question
