Support for access to emergency services by branch users in Normal Mode is
configured at the main office.
The key difference between the main office user and the branch user is the
route selected for the emergency call. An emergency call must be handed off
to the PSTN over a trunk at the central office that is geographically closest to
the caller — this means that there is normally an emergency trunk in the main
office, and one in each of the branch offices. An emergency call originating
from an SRG IP Phone must route from the main office Call Server to the
SRG so that the call can be sent on the SRG PSTN Trunks.
