  A. INVITE
  B. 180 Ringing
  C. 200 OK
  D. ACK
  E. RTP Media
  C. 200 OK

  ---

  In Early offer, SIP Send SDP in the invite, the other node will send the SDP in the 200 message.

• Question 313:

  When using LDAP synchronization to automatically create and synchronize Cisco Unified Communications Manager end users, which two LDAP attributes can be synchronized to directory URI? (Choose two.)

  A. emailaddress
  B. msRTCSIPuseraddress
  C. mail
  D. msRTCSIPprimaryuseraddress
  E. email
  C. mail
  D. msRTCSIPprimaryuseraddress

• Question 314:

  Which system location is used for intercluster Enhanced Location CAC on Cisco Unified Communications Manager?

  A. Hub_None
  B. Default
  C. Intercluster
  D. Phantom
  E. Shadow
  E. Shadow

  ---

  The shadow location is used to enable a SIP trunk to pass Enhanced Location CAC information such as location name and Video-Traffic-Class (discussed below), among other things, required for Enhanced Location CAC to function between clusters. In order to pass this location information across clusters, the SIP intercluster trunk (ICT) must be assigned to the "shadow" location. The shadow location cannot have a link to other locations, and therefore no bandwidth can be reserved between the shadow location and other locations. Any device other than a SIP ICT that is assigned to the shadow location will be treated as if it was associated to Hub_None. That is important to know because if a device other than a SIP ICT ends up in the shadow location, bandwidth deductions will be made from that device as if it were in Hub_None, and that could have varying effects depending on the location and links configuration.

• Question 315:

  When multiple greetings are enabled on Cisco Unity Express, which greeting will take the highest precedence?

  A. standard
  B. meeting
  C. busy
  D. closed
  E. internal
  B. meeting

  ---

  Meeting greeting has the highest priority because it is set by the user when he doesn't want to take the call and notices the caller he is online.

• Question 316:

  What is the maximum length of any numeric geographic area address in ITU recommendation E.164?

  A. 15
  B. 18
  C. 21
  D. 22
  E. 25
  A. 15

  ---

  E.164 defines a general format for international telephone numbers. Plan-conforming numbers are limited to a maximum of 15 digits. The presentation of numbers is usually prefixed with the character + (plus sign), indicating that the number includes the international country calling code (country code), and must typically be prefixed when dialing with the appropriate international call prefix, which is a trunk code to reach an international circuit from within the country of call origination.

• Question 317:

  Refer to the exhibit.

  

  Which SIP trunk deployment model is shown in this enterprise VoIP topology?

  A. mixed TDM and VoIP
  B. centralized
  C. hybrid
  D. traditional TDM
  E. distributed
  C. hybrid

  ---

  Hybrid SIP Trunk Model In a hybrid SIP trunk deployment, some of the businesses' sites conform to a distributed SIP trunk deployment model. In this model each site has direct SIP session connectivity to the IP PSTN, and other sites conform to a centralized SIP trunk deployment, accessing the IP PSTN through a central hub, which has SIP session connectivity to the IP PSTN (Figure 3). The hybrid SIP trunk deployment model may have multiple "central" hubs in different geographic regions, or for specific business functions, such as call centers.

• Question 318:

  Which statement describes how much of the DSP resources are reserved for video conference when voice-service dsp-reservation 40 is configured on a Cisco Integrated Router Generation 2 with packet voice and video digital signal processor 3?

  A. 60% of the total available DSP resources
  B. 40% of the total available DSP resources
  C. 50% of the total available DSP resources
  D. Video conferencing resources are reserved dynamically by Cisco IOS and cannot be changed.
  E. This command is used for voice resource reservation only.
  A. 60% of the total available DSP resources

• Question 319:

  Refer to the exhibit.

  

  A user is going through a series of dialing steps on a SIP Type B IP phone (for example, a Cisco 7975) to call an SCCP IP phone. Both phones are registered to the same Cisco Unified Communications Manager cluster. Assuming the calling SIP phone is associated with a SIP dial rule with a pattern value of 2001, which statement about how digits are forwarded to Cisco Unified Communications Manager for further call processing is true?

  A. As each digit is pressed on the SIP IP phone, it is sent to Cisco Unified Communications Manager in a SIP NOTIFY message as a KPML event.
  B. The SIP IP phone will wait for the interdigit timer to expire, and then send each digit to Cisco Unified Communications Manager as a separate KPML event in a SIP NOTIFY message.
  C. The SIP IP phone will wait for the interdigit timer to expire, or for the Dial softkey to be selected before sending all digits to Cisco Unified Communications Manager in a SIP INVITE message.
  D. The SIP IP phone will wait for the interdigit timer to expire, or for the Dial softkey to be selected before sending the first digit in a SIP INVITE and the subsequent digits in SIP INFORMATION messages.
  E. The SIP IP phone will wait for the interdigit timer to expire, and then send all digits to Cisco Unified Communications Manager in a SIP INVITE message.
  E. The SIP IP phone will wait for the interdigit timer to expire, and then send all digits to Cisco Unified Communications Manager in a SIP INVITE message.

  ---

  Cisco Type B SIP Phones offer functionality based SIP INVITE Message. Every key the end user presses triggers an individual SIP message. The first event is communicated with a SIP INVITE, but subsequent messages use SIP NOTIFY messages. The SIP NOTIFY messages send KPML events corresponding to any buttons or soft keys pressed by the user. Cisco Type B SIP IP Phones with SIP dial rules operate in the same manner as Cisco Type A phones with dial rules.

• Question 320:

  Refer the exhibit. Which description of the Cisco Unified Communication Manager cluster that produced these identify Trust List records is true?

  

  A. IP phones registered to this cluster have ITL and CTL files installed.
  B. It is mixed-mode cluster that uses tokenless solution.
  C. IP phones registered to this cluster have neither ITL nor CTL files installed.
  D. It is mixed-mode cluster that uses hardware USB eToken.
  E. IP phones registered to this cluster have only ITL file installed.
  D. It is mixed-mode cluster that uses hardware USB eToken.
