I have inherited responsibility for the phone system here and am a little "in-the-dark" about how to do this. We have the Lucent ACS 6054-P30 Module, a Lucent 60623 2 Slot Carrier, a Lucent 60557 308 EC Module and 10 4-line extensions.We are interested in adding Music on Hold but could not figure out where to get such an addition or what module we need to purchase. There is a receptacle for a standard audio jack to plug into that is marked Voice on Hold. Can someone tell me if we just buy any voice-on-hold system and plug it in, or is there a particular module we need to buy?
