After configuring several of our Aastra 6725ip phones to work with our Lync system, nearly half of them are now unable to power up via POE. The POE injectors blink over the port indicating that there is a short. The phones have been powered up 3-5 times in the past and are now unable to. Has anyone else experienced this trouble? Short of getting replacements (which would probably result in the same issue) is there a solution?
Thank you!
