When a user is added as a responder, Zenduty looks for all the configured contact methods within the user’s notification rules for that incident’s urgency level(high or low) and then alerts the user accordingly.

Note: If a user has configured multiple contacts for a single contact type(for example, two numbers within the SMS contact method, say 1234567890 and 9876543210, Zenduty notifies the first contact type seen within the user’s notification rules(i.e 1234567890) for that contact method.
