While pagers might seem like an outdated technology, there are still industries where at least some in the industry will require a pager. Just like any communications in Kaldus, the phone provider must provide national coverage for their pager line. All pager services must offer voicemail included with the service. Also unlimited incoming pages are also required. The pager service provider should offer a basic pager for free. And since there is a unified voicemail service, the pager will sound off at every incoming voicemail.
