CollabCorp is a global company with two clusters, emea.collab.corp and apac.collab.corp. URI dialing is implemented and working in each cluster. The company configured routing between clusters to make inter- cluster calls via URI, but this is not working as expected.
Which two configuration elements should be checked to resolve this issue? (Choose two.)

  1. intercluster trunk
  2. directory URI partition
  3. SIP route pattern
  4. calling search space and partition
  5. SIP trunk

Answer(s): C,E





Refer to the exhibit. A user dials 84969010 and observes that the call is not routed immediately. The administrator notices that after matching the fixed-length translation pattern, the call hits the \+! pattern and waits for interdigit timeout.
What should be configured to ensure that the call routes out immediately?

  1. Allow Device Override on the route pattern
  2. Do Not Wait For Interdigit Timeout On Subsequent Hops on the route pattern
  3. Do Not Wait For Interdigit Timeout On Subsequent Hops on the translation pattern
  4. Route Next Hop By Calling Party Number on the translation pattern

Answer(s): C



A customer is using a SIP trunk to route calls to ITSP. To decrease the possibility of downtime, the customer invested in a failover device. How does the customer ensure reachability to ITSP, so that if one device on ITSP fails, the calls will be routed to another device?

  1. Enable SIP Option Ping on the SIP profile.
  2. Monitor the link using network management tools, and if it fails, manually change the routing to another working device.
  3. Enable ANAT on the SIP profile.
  4. Enable transmit security status on the SIP security profile.

Answer(s): A



A customer routes PSTN calls to ITSP through a SIP trunk on Cisco UCM that forwards and receives calls to and from ITSP. ITSP is set to send an E.164 number when the customer's extension is four digits.
Which action should be taken to route the incoming calls to four-digit extensions?

  1. Configure a voice translation profile to map the E.164 number to four digits and assign it to the incoming dial-peer on Cisco Unified Border Element.
  2. Set the Significant Digits to 8 on the SIP trunk.
  3. Set the Significant Digits to 4 on the SIP trunk.
  4. Configure a voice translation rule to map the E.164 number to four digits and assign it to the incoming dial- peer on Cisco Unified Border Element.

Answer(s): C





Refer to the exhibit. A standard local route group is configured for long-distance calls. Calls from building A succeed, but calls from building B fail. On the system, each building has its own device pool. The DNA tool is used to test the configuration. How is this issue resolved?

  1. Change the partition of the route pattern.
  2. Add a sip trunk inside route group Standard Local Route Group.
  3. Modify the route pattern to add a prefix of 91.
  4. Add a local route group on the device pool configuration.

Answer(s): B
