Preventing calling the devs requires dev to front-load ops. Ops needs triage documents, remediation strategies, architectural and workflow diagrams, dependency charts, distributed tracing, intelligent logging, custom application metrics, and tests they can run during incidents to isolate causes.

The devs can do all of this on their own, teach ops how to use it, and then they'd only be called when it was a code issue. But as a dev, you probably don't know all of the above, so ops has to go to dev and be like, "hey y'all, if you don't want to be called, this is what we need."

And this is what DevOps is intended to fix: get everyone in a room, talk about problems, find solutions among everyone. If your org isn't doing this, you can start the change.
