We are having VOIP issues where voice will drop out in one direction of the call after the call has been up for a couple of minutes. When running the "show ip rtp header-compression" command we can see errors, but I can find no explanation of what these errors mean. The link is not congested, and is not seeing any errors or buffer drops on the router interface.
If anyone could suggest possible causes of these errors or further commands that might give more insite it would be greatly appreciated.
