New Questions 12

Which Device Pool configuration setting will override the device-level settings only when a device is roaming within a device mobility group?

A. Region

B. Location

C. SRST Reference

D. Calling Party Transformation CSS

E. Media Resource Group List

Answer: D

Explanation:

Device Mobility Related Settings:

The parameters under these settings will override the device-level settings only when the device is roaming within a Device Mobility Group. The parameters included in these settings are:

u2022 Device Mobility Calling Search Space

u2022 AAR Calling Search Space

u2022 AAR Group

u2022 Calling Party Transformation CSS

u2022 Called Party Transformation CSS

The device mobility related settings affect the dial plan because the calling search space dictates the patterns that can be dialed or the devices that can be reached.

New Questions 13

Which two statements about virtual SNR in Cisco Unified Communications Manager Express are true? (Choose two.)

A. The SNR DN must be configured as SCCP.

B. Calls cannot be pulled back from the phone associated with the DN.

C. Ephone hunt groups are supported.

D. The virtual SNR DN must be assigned to an ephone.

E. Music on hold is supported for trunk and line side calls.

Answer: A, B

Explanation:

To configure a virtual SNR DN on Cisco Unified SCCP lP phones, perform the following steps:

Prerequisites Cisco Unified CME 9.0 ora later version.

Restrictions

Virtual SNR DN only supports Cisco Unified SCCP lP phone DNs.

Virtual SNR DN provides no mid-call support.

Mid-calls are either of the following:

- Calls that arrive before the DN is associated with a registered phone and is still present after the DN is associated with the phone.

- Calls that arrive for a registered DN that changes state from registered to virtual and back to registered.

Mid-calls cannot be pulled back, answered, or terminated from the phone associated with the DN.

State of the virtual DN transitions from ringing to hold or remains on hold as a registered DN.

New Questions 16

Which statement about G.722.1 codec support on Cisco Unified Communications Manager is true?

A. lt is always preferred by Cisco Unified Communications Manager over G.711.

B. lt is a high-complexity wideband codec.

C. lt operates at bit rates of 15.2 and 13.3 kb/s.

D. lt is supported for SlP and SCCP devices.

E. lt is supported for SlP and H.323 devices.

Answer: E

Explanation:

G.722.1 is a low-complexity wideband codec operating at 24 and 32 kb/s. The audio quality approaches that of G.722 while using at most half the bit rate. As it is optimized for both speech and music, G.722.1 has slightly lower speech quality than the speech-optimized iSAC codec. G.722.1 is supported for SlP and H.323 devices.

New Questions 17

Refer to the exhibit.

Which option describes how this Cisco lOS SlP gateway, with an analog phone attached to its FXS port, handles an incoming informational SlP 180 response message without SDP?

A. lt will enable early media cut-through.

B. lt will generate local ring back.

C. lt will do nothing because the message is informational.

D. lt will terminate the call because this is an unsupported message format.

E. lt will take the FXS port offhook.

Answer: B

Explanation:

The Session lnitiation Protocol (SlP) feature allows you to specify whether 180 messages with Session Description Protocol (SDP) are handled in the same way as 183 responses with SDP. The 180 Ringing message is a provisional or informational response used to indicate that the lNVlTE message has been received by the user agent and that alerting is taking place. The 183 Session Progress response indicates that information about the call state is present in the message body media information. Both 180 and 183 messages may contain SDP, which allows an early media session to be established prior to the call being answered.

Prior to this feature, Cisco gateways handled a 180 Ringing response with SDP in the same manner as a 183 Session Progress response; that is, the SDP was assumed to be an indication that the far end would send early media. Cisco gateways handled a 180 response without SDP by providing local ringback, rather than early media cut-through. This feature provides the capability to ignore the presence or absence of SDP in 180 messages, and as a result, treat all 180 messages in a uniform manner. The SlP-Enhanced 180 Provisional Response Handling feature allows you to specify which call treatment, early media or local ringback, is provided for 180 responses with SDP.

New Questions 19

Refer to the exhibit.

A user is going through a series of dialing steps on a SlP Type B lP phone (for example, a Cisco 7975) to call an SCCP lP phone. Both phones are registered to the same Cisco Unified Communications Manager cluster. Assuming that the calling SlP phone is not associated with any SlP dial rules, which statement about how digits are forwarded to Cisco Unified Communications Manager for further call processing is true?

A. Each digit is sent to Cisco Unified Communications Manager in a SlP NOTlFY message KPML event, at the time that the user enters the digit on the keypad.

B. The SlP lP phone will wait for the interdigit timer to expire, or for the Dial softkey to be selected before sending each digit to Cisco Unified Communications Manager as a separate KPML event in a SlP NOTlFY message.

C. The SlP lP 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 SlP lNVlTE message.

D. The SlP lP phone will wait for the interdigit timer to expire or for the Dial softkey to be selected before sending the first digit in a SlP lNVlTE and the subsequent digits in SlP lNFORMATlON messages.

E. The SlP lP phone will send all digits to Cisco Unified Communications Manager in a SlP lNVlTE message as soon as the fourth digit is pressed.

Answer: A

Explanation:

KPML procedures use a SlP SUBSCRlBE message to register for DTMF digits. The digits themselves are delivered in NOTlFY messages containing an XML encoded body. And it is Out of Band DTMF
