Each analog port can support a device of maximum 1 REN.
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). The primary
purpose of displays is to give information about incoming calls. Where the Caller Display standard chosen
supports the delivery of text (extension name) as well as the number, both are delivered.
An analog extension port can be set for external Paging operation. It does not operate like a normal extension
and is connected to external equipment through an isolation device. The Port will always be busy so it cannot
be called directly and can only be accessed by using a paging feature. When not receiving a Page, the port will
remain silent. When being paged, the page tone is sent before the speech path is opened.
