Re: crypto delay (Notes from Non-meeting)

I don't think that's a viable option. The location information is used
for two different things:

- selecting the appropriate emergency call center that handles a
particular geographic region (PSAP in the US);

- providing the emergency call center with user location information

Clearly, the first requires location information as part of the call
setup and cannot be deferred until later in the call.
