Hello. I am administering a Mitel 3300 ICP. I have setup the ACD Silent Monitor feature on several IP phones, which allows the supervisors to listen to their call center agents' conversations. It has been working well for some time until recently. When a supervisor selects the silent monitor key and enters the extension of an agent who is in a call, the engaged tone plays. This issue occurs on all IP phones configured for silent monitoring. What could be the cause of the engaged tone playing and not the live call? Below are the current settings of silent monitoring as they appear in the Class of Service form:
ACD Silent Monitor Accept Yes
ACD Silent Monitor Accept Monitoring Non-Prime Lines No
ACD Silent Monitor Allowed Yes
ACD Silent Monitor Notification No
ACD Silent Monitor Accept Yes
ACD Silent Monitor Accept Monitoring Non-Prime Lines No
ACD Silent Monitor Allowed Yes
ACD Silent Monitor Notification No
