Just to make this clear, while the contact is attempted immediately, failure to make contact does not delay response, though success can hurry response. For example, if an unlocated alert is received via GEO satellites and they call your emergency contact number and they say, yes, you're of climbing so and so mountain, they may launch on that, so as to be in the area when the Doppler derived location is received a little later and thereby shortening response time.



I am not sure what you mean by this. You only register the beacon once, normally in your country of origin. Beacons are country coded and with few exceptions cannot be registered in countries other than for which they are coded. The registration location should have no impact on the initial SAR response which is alert location dependent.
