Greetings, We are currently running an Avaya IP office IP/PBX, which works pretty okay for our office. The challenge we have is that the headsets (1608-I) keeps on 'dying'. (They are on POE) I have researched online and discovered it could be the power module on the headsets that keeps burning. Am currently looking for someone who can repair the headsets(power modules) Kindly contact me offlist incase you know someone or you can do it. Regards, Butler Karechio
