8.5.1.2.2 Emergency State
If the UAs detect that their primary (external) proxy does not respond, they immediately
register to SAS and start routing calls to it.

8.5.1.2.3 Exiting Emergency and Returning to Normal State
Once the connection with the primary proxy is re-established, the following occurs:
UAs:
switch back to operate with the primary proxy.
SAS:
ignores REGISTER requests from the UAs, forcing the UAs to switch back to
the primary proxy.
Note:
This is applicable only if the 'SAS Survivability Mode' parameter is set to
'Always Emergency' (2).
