• Question 286:

  What is the most efficient way to configure a speed dial to number 1111 on multiple phones using the Self-Provisioning feature in Cisco UCM?

  A. Configure each phone with the same DN and then configure a speed dial of 1111 on one of the phones manually by navigating to Devices>Phones and modifying the phone. This will automatically replicate to all the other phones.
  B. Configure the phones with a phone button template that has speed dials then specify 1111 as a speed dial via BAT>Phones>Add/Update phones web page to specify the speed dial number after the phone is in Cisco UCM.
  C. Configure a universal device template that has speed dials in the phone button configuration field, then allow the user to specify 1111 as a speed dial via the Cisco Unified Communications Self Care Portal.
  D. Configure a universal device template that has speed dials in the phone button configuration field, then specify 1111 as a speed dial by editing the speed dial within the universal device template.
  D. Configure a universal device template that has speed dials in the phone button configuration field, then specify 1111 as a speed dial by editing the speed dial within the universal device template.

• Question 287:

  A collaboration engineer adds a voice gateway to Cisco UCM. The engineer creates a new gateway device in Cisco UCM, selects as the device type, and selects MGCP as the protocol.

  What must be done next to add the gateway to the Cisco UCM database?

  A. Select a device pool for the new gateway.
  B. Add the FQDN or hostname of the device.
  C. Configure the module in slot 0 of the new gateway.
  D. Select the DTMF relay type for the gateway.
  B. Add the FQDN or hostname of the device.

• Question 288:

  An engineer must configure a dial plan tor a new Cisco UCM cluster. Standard local route groups must be used for all local calls.

  After the route pattern, route list and route groups are configured, which settings must the engineer configure for the standard local route groups?

  A. device pool
  B. voice gateway
  C. trunk group
  D. SIP trunk
  A. device pool

• Question 289:

  Refer to the exhibit.

  

  An engineer configures ISDN on a voice gateway. The provider confirms that the PRI is configured with 10 channels the engineer ordered and is working from the provider side, but the engineer cannot get a B-channel to carry voice. The rest of the configuration for the serial interface and voice network is functioning correctly.

  Which actions must be taken to carry voice?

  A. The engineer must activate the controller card on the voice gateway before configuring the device.
  B. The engineer used a T1 interface but must use an E1 interface.
  C. The pri-group timeslots command must be 0-9 for the 10 channels because all values on a router start with 0.
  D. The engineer must manually revert the order of using the channels.
  D. The engineer must manually revert the order of using the channels.

• Question 290:

  Refer to the exhibit.

  Which codec should an engineer select for a call mode between "Dallas-REG" & "Austin-REG"?

  

  A. MP4A-LATM
  B. G.729
  C. OPUS
  D. G.711
  B. G.729

  ---

  Explanation

  The codec preference list for the "Dallas-REG" region is "Factory Default low loss". This list includes the following codecs in order of preference:

  G.729

  G.711

  OPUS

  MP4A-LATM

  The codec preference list for the "Austin-REG" region is "Factory Default low loss". This list includes the following codecs in order of preference:

  G.729

  G.711

  OPUS

  MP4A-LATM

  Since both regions have the same codec preference list, the codec that will be used for a call made between "Dallas-REG" and "Austin-REG" is G.729. G.729 is a narrowband speech codec that was developed by the ITU-T in 1988. It is a low-bitrate codec that provides good quality speech at a bitrate of 8 kbps. G.729 is widely used in VoIP applications and is the default codec for many VoIP systems. G.711 is a wideband speech codec that was developed by the ITU-T in 1972. It is a high-bitrate codec that provides excellent quality speech at a bitrate of 64 kbps. G.711 is not as widely used as G.729 due to its high bitrate requirements. OPUS is a lossy audio codec that was developed by the IETF in

  2012. It is a low-bitrate codec that provides good quality speech at a bitrate of 6 kbps. OPUS is widely used in VoIP applications and is the default codec for many VoIP systems. MP4A-LATM is a lossy audio codec that was developed by the IETF in 1999. It is a high-bitrate codec that provides excellent quality speech at a bitrate of 24 kbps. MP4A-LATM is not as widely used as G.729 or OPUS due to its high bitrate requirements.
