Good morning gjames,
To get you started, assuming the customer option on your switch for service observing is yes and you have vectoring make sure the "can be service observed" field is stroked to yes on the COR of the person you want to observe. Careful here, your key people may not want to be service observable, you may to assign a new COR to them just for this one field. Next, assign a service observe button to the phone you want to observe from. Remember, the observer's COR must be stroked yes for "can be a service observer". Assign feature codes for the listen/listen-talk functions.
To begin observing, the observer presses the Service Observing button plus the agent’s extension number. Initially, the observer is in listen-only mode. The observer presses the Service Observing button to toggle between listen-only and listen/talk mode. The lamp
indicates which mode the observer is in. To deactivate Service Observing, the observer hangs up, selects another call appearance, or presses the disconnect or release button. An observer can observe an agent who is not active on a call. The observer is in the wait state until the agent receives a call, then the observer is bridged onto the call.
