   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?

   • AConfigure 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.
   • BSet the Significant Digits to 8 on the SIP trunk.
   • CSet the Significant Digits to 4 on the SIP trunk.

   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?

   • AChange the partition of the route pattern.
   • BAdd a sip trunk inside route group Standard Local Route Group.
   • CModify the route pattern to add a prefix of 91.

9. Question 89 · 211 in bank

   

   Refer to the exhibit. For long-distance calls, users must prefix their dialed number with “91”. The translation pattern was created to strip the 91 as the PSTN expects a 10-digit number. The PSTN also requires the calling number to be set to 9195551234. However, the service provider has said calls with a different calling number are being received. How is this issue resolved?

   • AChange the partition of the translation pattern from none to pstn_pt.
   • BDisable Use Calling Party’s External Phone Number Mask on the route pattern.
   • CEnable Force Authorization Code on the route pattern.
   • DEnable Use Calling Party’s External Phone Number Mask on the translation pattern.

    A single site reports that when they dial select numbers, the call connects, but they do not get audio. The administrator finds that the calls are not routing out of the normal gateway but out of another site's gateway due to a TEHO configuration. What is the next step to diagnose and solve the issue?

    • AVerify that the route pattern has the correct calling-party transformation mask.
    • BVerify that IP routing is correct between the gateway and the IP phone.
    • CVerify that the dial peer of the gateway has the correct destination pattern configured.
    • DVerify that the route pattern is not blocking calls to the destination number.
