22. it needs to know which dial plan to use If the PBX uses the internal database it uses the dial plan of the selected extension The setting Caller ID determines weather to show the caller ID on outgoing calls If the caller ID is shown and the call is started on behalf of a known extension it will use the caller ID associated with that extension If the SOAP interface is being used the PBX will show the caller ID of the calling card account Dialog Permissions are described in Dialog Permissions 6 2 8 3 Application Server Application Server Number of digits for calling card ID Po Save 6 2 9 Paging 6 2 9 1 Purpose Paging means a one way audio communication from one caller to a potentially large group of listeners Typical applications include supermarkets hospitals or trains You may have several paging groups on one PBX that addresses different audiences For example you might have one paging account that calls a specific floor of the building and you might have another group that pages the whole building Intercom is a potentially two way communication between two participants Intercom is controlled by the feature codes Intercom In the previous version of the PBX those two features were both in the paging group In this version they have been separated There are two ways to implement paging The first way establishes regular calls to the paging recipients by using standard SIP calls indicating that the call
