Setting up SMS and voice messaging as contact methods

To send On-call escalation notifications as SMS or voice messages, you must configure Notify.

Configure the following items to use Notify with On-Call Scheduling:

You must add at least one Notify phone number to the On-Call Group number group. This group is configured by default to handle inbound SMS responses (via On-Call: Check Assignment Response) that accepts or rejects an on-call assignment and to handle outbound voice calls (via On-Call: Assign by Acknowledgement Voice) to accept or reject assignments.
You must configure workflows, such as the On-Call: Assign by Acknowledgement to drive escalations via SMS and Voice.
