An engineer set up and successfully tested a TEHO solution on the Cisco UCM. PSTN calls are routed correctly using the IP WAN as close to the final PSTN destination as possible. However, suddenly, calls start using the backup local gateway instead.
What is causing the issue?
- A . WAN connectivity
- B . LAN connectivity
- C . route pattern
- D . route list and route group
Refer to the exhibit.
Within the North American Numbering Plan, gateways located in Ottawa, Canada and marked as “YOW” are assigned to the Calling Party Transformation CSS NANP_CgPTP, which contains partition NANP_calling_xforms.
What is the calling-party number and the numbering type if the calling user +1613-555-1234 dials the number?
- A . calling number 613-555-1234 and numbering type “subscriber”
- B . calling number 011-1-613-555-1234 and numbering type “subscriber”
- C . calling number 011613-555-1234 and numbering type “international”
- D . calling number 613-555-1234 and numbering type “national”
Refer to the exhibit.
A user cannot call number 730. which Is an abbreviated number for 45730. The engineer recently configured a translation pattern In Cisco UCM. The newly configured translation pattern of 7XX prefixes the digits 45. The engineer uses DNA to troubleshoot the issue.
What is the reason for this problem?
- A . The abbreviated partition is missing from the calling search space.
- B . The translation pattern is blocking the call.
- C . The translation pattern Is misconfigured.
- D . Directory number 45730 is unknown to Cisco UCM.

A collaboration engineer investigates an issue where the user calls that match the local Jabber domain are routed back to Cisco UCM.
Which action resolves this problem?
- A . Check the check box to block the pattern for the local domain.
- B . Create another route SIP pattern for the local domain with the block pattern selected.
- C . Create a translation pattern to block calls to the local domain.
- D . Create a transformation pattern to block calls to the local domain.
Refer to the exhibit.

- A . Change the partition of the route pattern
- B . Add a sip trunk inside route group Standard Local Route Group.
- C . Modify the route pattern to add a prefix of 91
- D . Add a local route group on the device pool configuration.
Refer to the exhibit.
