Callers from a branch report getting busy tones intermittently when trying to reach colleagues in other office branches during peak hours. An engineer collects Cisco CallManager service traces to examine the situation.
The traces show:

50805567.000 |07:35:39.676 |SdlSig |StationOutputDisplayNotify |restart0 |StationD(1,100,63,6382) | StationCdpc(1,100,64,4725) |1,100,40,7.101980^*^* |[R:N-H:0,N:0,L:0,V:0,Z:0,D:0] TimeOutValue=10 Status=x807 UnicodeStatus= Locale=1 50805567.001 |07:35:39.676 |AppInfo | StationD: (0006382) DisplayNotify timeOutValue=10 notify=`x807' content=`Not Enough Bandwidth' ver=85720014.

What should be fixed to resolve the issue?

  1. class of service configuration
  2. geolocation configuration
  3. region configuration
  4. codec configuration

Answer(s): C



What is the purpose of Mobile and Remote Access (MRA) in the Cisco UCM architecture?

  1. Mobile and Remote Access is used to access Webex cloud services only if authenticated with on-premises LDAP service.
  2. Mobile and Remote Access is used to make secure PSTN calls by Cisco UCM only while on-premises authentication.
  3. Mobile and Remote Access is used to make B2B calls through Expressway registration.
  4. Mobile and Remote Access is used to access the collaboration services offered by Cisco UCM from off- premises network connections.

Answer(s): D



Which external DNS SRV record must be present for Mobile and Remote Access?

  2. _collab-edge._tls.example.com
  3. _collab-edge._tcp.example.com
  4. _cisco-uds._tls.example.com

When a call is delivered to a gateway, the calling and called party number must be adapted to the PSTN service requirements of the trunk group. If a call is destined locally, the + sign and the explicit country code must be replaced with a national prefix. For the same city or region, the local area code must be replaced by a local prefix as applicable. Assuming that a Cisco UCM has a SIP trunk to a New York gateway (area code 917), which two combinations of solutions localize the calling and called party for a New York phone user? (Choose two.)

  1. Configure the gateway to translate the calling number and apply it to the dial peer. Combine it with a translation profile for called numbers.
    !
    voice translation-rule 1
    rule 1 /^1917/ //
    rule 2 /^ [+]1917/ //
    !
    voice translation-profile strip+1
    translate calling 1
    !
  2. Configure two calling party transformation patterns:
    \+1917.CCCCCC, strip pre-dot, numbering type: subscriber
    \+!, strip pre-dot, numbering type: national
  3. Configure two called party transformation patterns:
    \+1917.XXXXXXX, strip pre-dot, numbering type: subscriber
    \+1.!, strip pre-dot, numbering type: national
  4. Configure the gateway to translate called numbers and apply it to the dial peer. Combine it with a translation profile for calling numbers.
    !
    voice translation-rule 1
    rule 1 /^1917/ //
    rule 2 /^[+]1917/ //
    !
    voice translation-profile strip+1
    translate called 1
    !
  5. Configure two calling party transformation patterns:
    \+1917.XXXXXXX, strip pre-dot, numbering type: subscriber
    \+1.!, strip pre-dot, numbering type: national

Answer(s): C,E



A customer reports that the Cisco UCM toll-fraud prevention does not work correctly, and the customer is receiving charges for unapproved international calls as a result.
Which two configuration changes resolve the issues? (Choose two.)

  1. Use Cisco Unified Border Element to debug the calls.
  2. Disable call forwarding on the phone.
  3. Make the calls route through a firewall.
  4. Mark patterns as off-net or on-net.
  5. Modify the Block OffNet to OffNet Transfer service parameter.

Answer(s): D,E
