Note: On analog ports, call information is sent while the phone is ringing, and cannot be updated during a call or set on an outbound call (the phone may do a local match but this is not controlled by the IP Office - an analog extension port can be set for external Paging operation). The Port will always be busy so it cannot be called directly and can only be accessed by using a shortcode (with primary purpose of displays is to give information about incoming calls). When not receiving a Page the port will remain silent or when being paged the page tone is sent before the speech path is opened (with Caller Display standard chosen supports the delivery of text “extension name” as well as the number, both are delivered). It does not operate like a normal extension and is connected to external equipment through an isolation device.
