Query: Does not meet my needs

My major complaint with this product is the voice activated feature. The amplifier turns itself off when no one is talking. It's a good concept in order to save battery life but I found that many times it would turn itself off in the middle of a conversation if the person on line was not loud enough. I found the unit would even turn itself off during the muzak while on hold. When it does turn back on it will lose the first word of the speaker. If there was a provision to adjust the sensitivity or disable the voice activation this would be a much better product.
