Supervisors and administrators can broadcast audio messages to digital and IP phones with loudspeakers without having to install a separate paging system. Paging can be to individual phones or groups of phones.
Implementation engineers can configure analog extension ports to an external overhead paging system, usually through an adapter, so that a port can be included in a paging group to permit mixed phone and overhead paging.
The default configured minimum value of paging volume is 10. The value cannot be decreased but increased up to 16. The configured value is retained after restart or power outage.
Some digital and IP phones can answer a page by pressing a key while the page is going on, this stops the page and turns it into a normal call.
