Ok, this is a bit dated but I am stumped. I have a customer that has a 200 EL running a call center and uses Melco KMT-330ATs to monitor the agents. They stopped working about a year ago, so they say (They are a new customer for us). I have replaced one of the units and can only hear the outside party while monitoring the line. Is there something that I have done wrong or some way to troubleshoot these things? The guys that installed the system made their own "Y" line cords where one pair connects to the handset port and the other powers the phone. The agents all use headsets, could thid be part of the problem? Customer swears that it worked before and that nothing about the setup has changed. Just gradual hardware failure over time.
I gave my solution of upgrading to a 3300 to be able to natively monitor the agents, hasn't happened yet.
