Has anyone experienced their IP Phones fading out during long duration calls. I have heard of a couple of phone calls here that when they are on the phone for more than 20 minutes the volume to the other end begins fading out.
The signal strength seems to be fine for the first 20 to 30 minutes of the call conversation, but thereafter the audio degrades. How can we check that the signal strength on the gateway? We have a CMM module for the 6500. Thanks in advance!
