I just purchased a bogen PA system for my BCM50 phone system (TAMB2 , GA2, & speaker). I was wondering if there is any configuration that you have to do to set up the Bogen TAMB2 up to the BCM50? Right now I have a connected to an analog station and when I access the paging system by dialing the analog station number,I can only hear a tone(Bogens tone; not Nortels tone)coming out of the ear of the phone and not the actual Nortel phone set itself. Note: I currently do not have the GA2 or ceiling speaker; I thought I could try it with my voice internally coming out of my Nortel T7316E set. If anyone could explain to me how this system works or how to program it so that it works right and to get my voice to come of all speakers using the Bogen system, that would be great! Thanks in advance!
