The device forwards the 200 OK to the subscriber (without the XML body). The call flow is
shown below:
Figure 38-10: Interoperability with BroadWorks Registration Process
The device saves the users in its registration database with their phone numbers and
extensions, enabling future routing to these destinations during survivability mode when
communication with the BroadWorks server is lost. When in survivability mode, the device
routes the call to the Contact associated with the dialed phone number or extension
number in the registration database.

38.6.2 Configuring BroadSoft's Shared Phone Line Call Appearance for
Survivability
The device can provide redundancy for BroadSoft's Shared Call Appearance feature.
When the BroadSoft application server switch (AS) fails or does not respond, or when the
network connection between the device and the BroadSoft AS is down, the device
manages the Shared Call Appearance feature for the SIP clients.
The feature is supported by configuring a primary extension and associating it with
secondary extensions (i.e., shared lines) so that incoming calls to the primary extension
also ring at the secondary extensions. The call is established with the first extension to
answer the call and consequently, the ringing at the other extensions stop. For example,
assume primary extension number 600 is shared with secondary extensions 601 and 602.
In the case of an incoming call to 600, all three phone extensions ring simultaneously,
