Paging is not vailable just with CCM and IP Phones. You have to use 3rd party paging devices.Broadcast Paging:Allows the user to broadcast announcements through overhead speakers. Zone paging provides multiple zone support. Broadcast paging support is achieved through configuration of one or more Foreign Exchange Station (FXS) gateway ports configured within CallManager with specific directory numbers on each port. A 3rd-party product attached to the FXS ports automatically answers the calls and distributes the audio to broadcast speakers. In addition, there are several 3rd-party applications available which utilize the IP Phone Services XML API to envoke forms of Broadcast/Group Paging. CCM supports third party overhead paging equipment (i.e. Valcom) can connect through FXS ports or via IP connections using access codes. Cisco CallManager Express supports multicast page to IP phones and also supports external 3rd party paging systems connected to voice ports on Cisco CallManager Express router.Third party info: Valcom's V-8820 overhead paging system includes a compatible VoIP overhead paging controller and IP speakers (www.valcom.com).
