<p class=MsoNormal style='text-autospace:none'><font size=3 face=Verdana><span
style='font-size:12.0pt;font-family:Verdana'>This approach is preferred when a
phone is located within a site whose WAN link is down. If the site is equipped
with Survivable Remote Site Telephony, the phone (and its co-located PSTN
gateway) will re-register with the co-located SRST router. The phone is then
able to receive calls placed to its PSTN DID number.<o:p></o:p></span></font></p>

destination is the corresponding PSTN DID number of the original destination

<p class=MsoNormal style='text-autospace:none'><font size=3 face=Verdana><span
style='font-size:12.0pt;font-family:Verdana'>Cisco Unified CallManager attempts
to route the call to the configured destination number by using the called DN's
CFUR calling search space. The CFUR calling search space is configured on the
target phone and is used by all devices calling the unregistered phone. This
means that all calling devices will use the same combination of route pattern,
route list, route group, and gateway to place the call, and that all CFUR calls
to a given unregistered device will be routed through the same unique gateway
regardless of where the calling phone is located. Cisco recommends that you
select a centralized gateway as the egress point to the PSTN for CFUR calls and
that you configure the CFUR calling search space to route calls to the CFUR
destination to this centralized gateway.<o:p></o:p></span></font></p>

<p class=MsoNormal style='text-autospace:none'><font size=3 face=Verdana><span
style='font-size:12.0pt;font-family:Verdana'>The Call Forward Unregistered
functionality can result in telephony routing loops if a phone is unregistered
while the gateway associated with the phone's DID number is still under control
of Cisco Unified CallManager, as is the case if a phone is simply disconnected
from the network. In such a case, the initial call to the phone would prompt
the system to attempt a first CFUR call to the phone's DID through the PSTN.
The resulting incoming PSTN call would in turn trigger another CFUR attempt to
reach the same phone's DN, triggering yet another CFUR call from the central
PSTN gateway through the PSTN. This cycle could repeat itself until system
resources are exhausted.<o:p></o:p></span></font></p>

style='font-size:12.0pt;font-family:Verdana'>MaximumForwardUnRegisteredHopsToDn
controls the maximum number of CFUR calls that are allowed for a DN at the same
time. The default value of 0 means the counter is disabled. If any DNs are
configured to reroute CFUR calls through the PSTN, loop prevention is required.
Configuring this service parameter to a value of 1 would stop CFUR attempts as
soon as a single call is placed through the CFUR mechanism. This setting would
also allow only one call to be forwarded to voicemail, if CFUR is so
configured. Configuring this service parameter to a value of 2 would allow for
up to two simultaneous callers to reach the voicemail of a DN whose CFUR
setting is configured for voicemail, while also limiting potential loops to two
for DNs whose CFUR configuration sends calls through the PSTN.<o:p></o:p></span></font></p>

style='font-size:12.0pt;font-family:Verdana'>Note Extension Mobility DNs should
not be configured to send Call Forward Unregistered calls to the PSTN DID
associated with the DN. The DNs of Extension Mobility profiles in the
logged-out state are deemed to be unregistered, therefore any calls to the PSTN
DID number of a logged-out DN would trigger a routing loop. To ensure that
calls made to Extension Mobility DNs in the logged-out state are sent to
voicemail, ensure that their corresponding Call Forward Unregistered parameters
are configured to send calls to voicemail. <o:p></o:p></span></font></p>
