. Apart from that, an emergency call shouldn't be
any easier than a normal call, the phone still needs to do all the basic GSM
networking things (signalling etc) before a call is even possible.
+1 to that.
Actually it might even be a bit "harder" because although the normal
call has already been developped and tested, but the emergency code
probably not either. (Or if written it's not tested ... it's not like
we can easily dial the emergency service 50 times to test code paths
on real networks for testing ...)
