[cisco-voip] Cisco 7942 phone Echoing.

[Ryan Huff]

I'm assuming you're dealing with TDM/analog technologies here. More often than not you're up against something called, "Talker's Echo" in which the local talker is hearing their voice duplicated back on their receiver. Many times, this comes from too much power coming from the local gateway and the excess signal is reflected back at the gateway from the PSTN.

If the the far-end is hearing an echo, it is generally due to equipment at the far end (nothing you can usually control).

To try and reduce local end echo / signal duplication; go into the configuration of the voice port paired with the interface for the voice card (Ex. voice-port 0/0/1:23) and reduce the input gain (Ex. input gain -3).

Thanks,

Ryan

Let me ask you this; when a user talks, are they hearing their own voice echoed back, OR is the far end (called party) hearing the talker's (calling party) voice twice in a way that sounds like an echo?

Thanks,

Ryan
