I have a user saying that he cannot hear his own voice in the handset when he talks on his Cisco 7940G IP phone. First off, is there a term for that particular sound -- the sound of your own voice in the handset? It needs to be strong enough so that you know how loud you are talking. But not too strong.
Second, what settings on the Call Manager (Cisco 2850) would affect this aspect of sound? Is this involved with the echo settings? (We have tweaked those extensively -- input gain, output attenuation, etc.) Is it perhaps a simple handset volume setting? (I tried, but the user says that did not fix the problem.)
