Arama Office Phone Headset Mono w/ Noise Canceling Mic for Polycom Mitel AVAYA Aastra Adtran Alcatel Lucent Allworx AltiGen Comdial Digium Gigaset InterTel MiVoice Plantronics

I tried this with a Digium phone and had to stop using it. It worked good for a while. But now, sometimes the microphone would work and sometimes it didn't. When it didn't work, when I talked all anybody on the call could hear was loud noise that did not sound like speech. I would hang up call back in and it would work for a while. Sometimes it sounded good at first on a new call and then fail some minutes later. Other times it would work fine. Fiddling with the connector did not address it (it was not a loose connector). Several people have suggested I pay a little more for a quality headset. I will try that now. Just sorry I wasted my money on this.
