We have an AGPTEK Call Center Headset that we want to use with a VVX 300 phone. However, there is a noticeable echo happening when we use it. When I use the headset to call someone else or if that person calls me, that person hears an echo on their phone and I do not. Echo Cancellation is enabled on both phones. It was worse without it.
I also tried using a cell phone to call the VVX 300 and I can hear an echo as well. Is there anyway I can remedy this? If not, do you have a recommended headset to use for this phone?
