840102 - Expose _isEmergencyNumber() to the content

Status: RESOLVED WONTFIX

(Core :: DOM: Device Interfaces, defect)

Description

[Etienne Segonzac (:etienne)]

+++ This bug was initially created as a clone of Bug #829581 +++

See https://mxr.mozilla.org/mozilla-central/source/dom/system/gonk/ril_worker.js#2767

As discussed on bug 829581, we apparently need to check on the Gaia side if a number is an emergency number in order to disable the airplane mode.

Why do we need to expose that to the content? Can't we simply have the RIL disable airplane mode if an emergency number is called?

Fine by me, should the Dialer try to dialEmergency every number while in Airplane mode then?

Note that we will probably inspect the call.state to see if we should display the "hey, you're in airplane mode" dialog or show the call screen, thus checking if it was an emergency number on the gaia side.

What's the decision there? Does this need platform support or not?

Yes.

Not sure I understand what you meant.

Closing since we're going to do things differently.
