• Question 141:

  An outbound call is in progress through a Cisco Unified Border Element using G729r8 codec. And it is dropped after 60 minutes.

  A. Configure the voice-class sip midcall-signaling block command on the outbound dial peer.
  B. Configure the midcall-signaling preserve-codec under voice service voip.
  C. Configure the voice class-codec command with G711u and G729r8 codecs on the outbound dial peer.
  D. Configure the voice-class sip midcall-signaling preserve-codec command on the outbound 247dial peer.
  E. Configure the midcall-signaling preserve-codec command under each outbound ITSP dial peer.
  F. Configure the midcall-signaling passthru media-change command under voice service voip.
  B. Configure the midcall-signaling preserve-codec under voice service voip.
  D. Configure the voice-class sip midcall-signaling preserve-codec command on the outbound 247dial peer.

• Question 142:

  When a Cisco IOS gatekeeper receives an ARQ from a registered endpoint, what is the first step it will take in an attempt to resolve the destination address?

  A. Check to see if the destination address is locally registered.
  B. Check to see if the destination address matches the technology prefix.
  C. Check to see if the destination address matches the local zone prefix.
  D. Check to see if the destination address matches the remote zone prefix.
  E. Check to see if the destination address matches the default technology prefix.
  B. Check to see if the destination address matches the technology prefix.

  Admission Request (ARQ) and Location Request (LRQ) are the two H.225 Registration, Admission, Status (RAS) messages that trigger a gatekeeper to initiate the call routing decision process. ARQ--Local zone messages that are sent by

  H.323 endpoints (usually gateways) to the Cisco gatekeeper. Gatekeepers receive ARQs from an endpoint if.

  -A local zone endpoint initiates a call. OR

  - A local zone endpoint request permission to admit an incoming call.

• Question 143:

  Which two file transfer protocols are used to send Call Detail Record flat files to third-party billing servers? (Choose two.)

  A. SCP
  B. SFTP
  C. TFTP
  D. FTP
  E. SOAP/HTTPS
  F. FTP over SSL
  B. SFTP
  D. FTP

• Question 144:

  Which Cisco Unity Connection call handler greeting, when enabled, overrides all other greetings?

  A. holiday
  B. closed
  C. internal
  D. busy
  E. alternate
  E. alternate

  ---

  An Alternate greeting might be enabled to override the Standard Greeting during certain times, because it is a personal greeting used for specific purpose.

• Question 145:

  Which two search scope options are removed from a directory handler when you check the "voice enabled" check box? (Choose two.)

  A. Class of Service
  B. System Distribution List
  C. Search Space
  D. Partition
  E. Phone System
  A. Class of Service
  B. System Distribution List

  ---

  You can configure the scope of a directory handler to define the objects that callers who reach the directory handler can find or hear. For phone directory handlers, you can set the scope to the entire server, to a particular class of service, to a system distribution list, or to a search space (either inherited from the call or specified for the directory handler). For voice-enabled directory handlers, you can set the scope to the entire server or to a search space (either inherited from the call or specified for the directory handler). When callers search a directory handler for a particular name, if the scope of the directory handler is set to a search space, Cisco Unity Connection searches each partition in the search space and returns a list of all of the objects that match the name.
