|Working with Pagers / About Vocera Paging|
Assign DID numbers to users who frequently send pages so that page recipients can return calls directly to the Vocera device.
When users have DID numbers, recipients of pages can return calls directly to the Vocera device without going through the guest access number.
DID numbers provide more convenient paging callbacks for recipients. In addition, some pagers cannot properly format a message containing a phone number with more than 10 digits, so DID numbers may be less confusing to the recipient of the page.
