Repeated calls not getting through in Sleep focus

Hey kallekilponen, just to be sure, was the second call made within the 3-minute mark? If it was, we recommend contacting Apple Support to look into this with you: Get Support

All the best.

Hello kallekilponen,

Welcome to Apple Support Communities. In order for repeated calls to go through while enabling Focus on your iPhone, follow these steps:

Allow or silence notifications from specific people during a Focus

1- Go to Settings  > Focus, then choose a Focus—for example, Do Not Disturb, Personal, Sleep, or Work.

2- Tap People (or tap Choose People), then do one of the following: 

• Allow specific people: Tap Allow Notifications From, tap , then select from your contacts.

You can also turn on options to allow calls from certain groups of people and allow repeated calls (two or more calls from the same person within 3 minutes).
