Refer to the exhibit. Which three events happen When Alice calls [email protected] and the URI lookup policy on the Cisco Unified CM server has been set to case insensitive? (Choose three)
A. The RTP server routes the call to [email protected] because remote URIs have priority
B. The RTP sever looks up to see if [email protected] is associated to a local number
C. The San Jose server calls [email protected] upon receiving the invite request
D. The San Jose server provide carol’s directory URI using ILS exchange
E. The RTP server sends the call to [email protected] because it has priority
F. The RTP server drops the call because it has two identical matches
Cisco Unified Communications Manager uses the following logic to route calls that are placed to a directory
URI:
• Cisco Unified Communications Manager checks if the dial string is numeric according to the Dial String
Interpretation policy. If the dial string is numeric, Cisco Unified Communications Managerroutes the
call as a directory number.
• Else, Cisco Unified Communications Manager checks local calling search spaces and the local directory
URI lookup table to see if the directory URI is in the local cluster. If the directory URI is on cluster,
Cisco Unified Communications Manager routes the call to the appropriate endpoint.
• Else, Cisco Unified Communications Manager checksif the directory URI existsin a learned or imported
catalog. If the directory URI is in a URI catalog,Cisco Unified Communications Manager tries to match
the route string for the catalog to a SIP route pattern. If a matching SIP route pattern is found, Cisco
Unified Communications Manager routes the call to the trunk that is associated with that route pattern.
• Else, if a matching SIP route pattern was found, and the route fails, Cisco Unified Communications
Manager checks if a PSTN failover exists for the directory URI. If a PSTN failover exists,Cisco Unified
Communications Manager uses the calling party’s AAR CSS to route the call to the PSTN failover
number.
• Else, Cisco Unified Communications Manager tries to match the host portion of the directory URI to a
SIProute pattern. If the host portion matches aSIProute pattern, Cisco Unified Communications Manager
routes the call to the SIP trunk that is associated to that route pattern.
• Else, Cisco Unified Communications Manager blocks the call.
