@Skalman This is unrelated. What I looked at is dialing (and getting the right default) emergency numbers in the locked shell. Most prominent missing bit her is Add emergency numbers based on location (!705) · Merge requests · GNOME / Calls · GitLab but again: this is in no way related to dialing any emergency numbers in calls itself.
If I understand @nerd7473 correctly you dialed 911 in the calls application and that didn’t work, right? In that case this is either rooted in calls or the modem or your carrier (i.e. it might be that no calls worked at that point).
Logs of the situation would be helpful for the calls maintainers to diagnose such things.
