Bug 1038701 - [US] Support for ICE Contacts in Lockscreen/Emergency call

Do you want to rethink this one? :) For example, I think it is useful to know that the calling party is occupied attending another call (NumberIsBusy error) so the use can retry it after some time, for example. Or that the call to an ICE contact cannot be established because the phone is in airplane mode.

On the other hand, didn't we want to show the right detailed error message in case of dialEmergency() (NoNetwork error in case of going through a tunnel, etc.).

In my opinion the more information we provide the user with about the problem to establish the call, the better for the user. Mainly "in case of an emergency" :) But you decide :) Thanks!
