I would like to use Andrea Electronics ANC-750 headsets with Mitel 5215 and 5220 IP Phones. I purchased a Headset Buddy (01-PC35-RJ9A): adapter that purportedly supports this. At one point I was able to hear dial tone through the headset with the adapter (and the phone in headset mode), but the other party could never hear me in a call. I've tried Andrea's APS-100 (auxiliary power supply) in case the mic is under powered. Now for some reason, I can't get audio coming or going with the headset (with or without the APS-100).
ideas?
Thank you!
