QUESTION NO:7

Refer to the exhibit.

When a Cisco IP Communicator phone roams from San Jose (SJ) to RTP, the Cisco IP Communicator physical location and the device mobility group change from SJ to RTP All route patterns are assigned a route list that points to the local route group All device pools are configured to use the local route group Which statement is true when the roaming phone places an AAR call?

A. Since globalized call routing is not configured, then the SJ gateway will be used in this case

B. The phone will use the AAR CSS that contains the SJ_PSTN partition. The call will egress at the SJ gateway

C. The phone will use the AAR CSS that contains the RTP_PSTN partition. The call will egress at the SJ gateway

D. The phone will use the AAR CSS that contains the SJ_PSTN partition. The call will egress at the RTP gateway.

E. The phone will use the AAR CSS that contains the RTP_PSTN partition The call will egress at the RTP gateway

Answer: D Explanation:

Cisco Unified Communications Manager Version 7.0 introduced the Local Route Group feature. When using local route groups, gateway selection is totally independent of the matched route pattern and referenced route list and routegroup. The use of the Local Route Group feature makes no changes regarding roaming-sensitive settings. The application of these settings always makes sense when roaming between sites. The settings have no influence to the gateway selection and the dial rules that a user must follow. However, the dial planrelated part of Device Mobility changes substantially withthe new dial plan concept, This concept allows a roaming user to follow the home dial rules for external calls but use the local gateway of the roaming site In this case, When the device mobility group is not the same for San Jose and RTP, the Device Mobility related settings are not applied. The phone device keeps its San Jose-specific configuration Despite the San Jose-specific configuration on the phone, the PSTN calls that originate from the roaming phone are routed via the local PSTN gateway (RTP GW) and are based on the route list and device pool local route group settings. The San Jose-specific dial plan is used. Also, AAR remains configured with the San Jose-specific configuration, but if the San Jose dial plan and San Jose AAR CSS permit and if the AAR group contains the prefix that can be applied in RTP, then AAR can work

QUESTION NO:14

Refer to the exhibit.

Refer to the exhibit. The exhibit shows the output of debug isdn q931. An inbound PSTN call was received by a SIP gateway that is reachable via a SIP trunk that is configured in Cisco Unified Communications Manager. The call failed to ring extension 3001. If the phone at extension 3001 is registered and reachable through the gateway inbound CSS, which three actions can resolve this issue? (Choose three.)

A. Change the significant digits for inbound calls to 4 on the SIP trunk configuration in Cisco Unified Communications Manager.

B. Configure the digit strip 4 on the SIP trunk under Incoming Called Party Settings in Cisco Unified Communications Manager.

C. Configure a translation pattern in Cisco Unified Communications Manager that can be accessed by the trunk CSS to truncate the called number to four digits.

D. Configure a called-party transformation CSS on the gateway in Cisco Unified Communications Manager that includes a pattern that transforms the number from ten digits to four digits.

E. Configure a voice translation profile in the SIP Cisco IOS gateway with a voice translation rule

that truncates the number from ten digits to four digits.

F. Configure the Cisco IOS command num-exp 2288223001 3001 on the gateway ISDN interface.

QUESTION NO:3

Which statement about device mobility is true?

A. When local route groups are used, there is no need to conjure device mobility groups or phone device CSSs as long as phone line CSSs are used.

B. When local route groups are used, you must configure device mobility groups and phone device CSSs.

C. When the device mobility group at the home device pool and roaming device pool are not the same, the Phone will keep the home region.

D. When device mobility groups at the home device pool and roaming device pool are the same, the phone will keep the home MRGL setting.

Answer: A Explanation:

QUESTION NO:4

Refer to the SDI trace in the exhibit A PSTN call arrived at the MGCP gateway that is shown in the SDI trace. If the caller ID that is displayed on the IP phone is 087071 222 and the HQ_clng pty_CSS contains the HQ_cing_pty_Pt partition, which exhibit shows the correct gateway digit manipulation”?

A. Exhibit A

B. Exhibit B

C. Exhibit C

D. Exhibit D

Answer: D Explanation: Explanation-Actual incoming number is 14-087071 222 but next to this information in trace we can see two digits are stripped which is international code hence D is valid answer.
