Whitelisting

Phone/SMS Alert Whitelisting

The following phone numbers are used to send out phone call alerts:

+1 415 200 2451

+44 7400 213056(for UK, Netherlands, Germany, Belgium and Portugal).

You can add these phone numbers to Do-Not-Disturb exceptions so that Zenduty phone alerts aren’t supressed whenever you have DND activated on your phone.

Alternatively, you can scan the following QR code to get the numbers in a vCard contact format, to easily add them to your whitelist. (Or download the vCard directly here)
