I downloaded the vCard with PagerDuty’s outgoing numbers about a year ago. This has identified PD calls very reliably, and is necessary for me to override Do Not Disturb mode on my phone.
Today I was paged by a new number that wasn’t recognized by my phone. I downloaded the latest vCard, and it does include the number I was called from.
How can I be notified when the vCard changes, so I can make sure I recognize PD calls?
