Yes but a landline call, made over a 5g modem connection is not a GSM phone call, it is a sip data call that gets separated out to the emergency system at the isps end, its a higher priority stream than data, but its still data. They didn’t work.

They could have made the modems use GSM phone routing for emergency calls, but they don’t. It’s all sip data.
