End users at a new site report being unable to hear the remote party when calling or being called by users at headquarters. Calls to and from the PSTN work as expected. To investigate the SIP signaling to troubleshoot the problem, which field can provide a hint for troubleshooting?  Contact: header of the 200 OK response  Allow: header if the 200 OK response  o= line of SDP content  c= line of SDP content Q24. Where on Cisco Unified Communications Manager do you configure the standard local route group for a group of devices?  System > Location Info  Call Routing > Route/Hunt > Local Route Group Names  System > Device Pool  Call Routing > Emergency Location > Emergency Location (ELIN) Groups Section: Call Control and Dial PlanningExplanation/Reference: https://www.uccollabing.com/configuring-standard-local-route-group-cucm/Q25. When locations-based Call Admission Control denies the call, which two masks can AAR apply when routing the call through the PSTN? (Choose two.)  AAR destination mask  called party transform mask  external phone number mask  +E.164 alternate number mask  enterrise alternate number mask Reference:https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/collab10/collab10/dialplan.htmlQ26. A customer is using a SIP trunk to route calls to ITSP to decrease the possibility of downtime, the customer invested in a failover device How does the customer ensure reachability to ITSP, so that if one device on ITSP fails, the calls will be routed to another device?  Enable transmit security status on the SIP security profile  Enable ANAT on the SIP profile.  Monitor the link using network management toots, and if it fails, manually change the routing to another working device.  Enable SIP Option Ping on the SIP profile. Q27. An engineer set up and successfully tested a TEHO solution on the Cisco UCM. PSTN calls are routed correctly using the IP WAN as close to the final PSTN destination as possible. However, suddenly, calls start using the backup local gateway instead. What is causing the issue?  WAN connectivity  LAN connectivity  route pattern  route list and route group Q28. What is first preference condition matched in a SIP-enabled incoming dial peer?  incoming uri  target carrier-id  answer-address  incoming called-number Reference:https://www.cisco.com/c/en/us/support/docs/voice/ip-telephony-voice-over-ip-voip/211306-In- Depth-Explanation-of-Cisco-IOS-and-IO.html#anc8Q29. An engineer is troubleshooting Cisco Device Mobility and find that the phone has roamed to a building that is assigned to a different device pool but has not changed its device pool accordingly What action resolves the issue?  Set correct Location under Current Device Mobility Settings  Enable SRST under Current Device Mobility Settings  Set the correct subnet under Device Mobility Info.  Set Device CSS under Current Device Mobility Settings. Q30. Refer to the exhibit.Users report that when they dial the emergency number 9911 from any internal phone, it takes a long time to connect with the emergency operator. Which action resolves this issue?  Adjust the service parameter T302 timet to the desired value.  Adjust the service parameter T204 timer to the desired value.  Check the Urgent Priority check box under 9.911 pattern.  Point the emergency pattern directly to the PSTN gateway. Q31. Which description of RTP timestamps or sequence numbers is true?  The sequence number is used to detect losses.  Timestamps increase by the time “carrying” by a packet.  Sequence numbers increase by four for each RTP packet transmitted.  The timestamp is used to place the incoming audio and video packets in the correct timing order (playout delay compensation).Q32. Refer to the exhibit.An administrator is troubleshooting why users are not hearing audio when dialing long distance numbers across their Cisco Unified Border Element. The customer’s carrier has a requirement that dialing long distance requires an access code to be entered. Looking at the exhibit, what two actions can be taken to correct signaling? (Choose two.)  Enable PRACK.  Enable Early Offer on the Cisco Unified Border Element.  Enable the supplementary-service media-renegotiate command.  Enable Media Flow Around  Enable Mid-Call Signaling Consumption. Q33. Refer to the exhibit.In an active SIP call between phone user A and phone user B, phone A initiates a call transfer to phone user C.Which two scenarios are correct? (Choose two.)  Phone_A sends a SIP-REFER message to the Cisco Unified Communications Manager with Phone_C information in the Refer-To section.  Phone_B sends a SIP-REFER message to the Cisco Unified CM with Phone_C information in the Refer-To section.  As soon as Phone_A presses the Transfer button for the first time, Phone_B hears the MOH and the MOH audio is chosen from Phone_B User Hold MOH Audio Source settings.  As soon as Phone_A presses the Transfer button for the first time, Phone_B hears the music on hold and the MOH audio is chosen from Phone_A Network Hold MOH Audio Source settings.  As soon as Phone_A presses the Transfer button for the first time, Phone_B hears the MOH and the MOH audio is chosen from Phone_A User Hold MOH Audio Source settings. Q34. What is first preference condition matched in a SIP-enabled incoming dial peer?  incoming uri  target carrier-id  answer-address  incoming called-number Section: Signaling and Media ProtocolsExplanation/Reference: https://www.cisco.com/c/en/us/support/docs/voice/ip-telephony-voice-over-ip-voip/211306-In- Depth-Explanation-of-Cisco-IOS-and-IO.html#anc8Q35. Refer to the exhibit.Outbound calls to the service provider cause intermittent errors due to a codec mismatch. The internal network sends early offer SDP that contains only G.711 A-law. The service provider reports that some destinations support only G.711 A-law while others support only iLBC. The service provider also allows only 20 active calls at a time Which configuration allows successful media negotiation for all calls using outbound dial peers 5002 and 5003?  Option A  Option B  Option C  Option D Q36. When configuring hunt groups, where do you add the individual directory numbers that will be part of the group?  route group  line group  hunt list  hunt pilot Section: Cisco Unified CM Call Control FeaturesExplanation/Reference: https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/12_0_1/systemConfig/ cucm_b_system-configuration-guide-1201/cucm_b_system-configuration-guide-1201_chapter_010101.htmlQ37. An engineer is configuring a call park feature in Cisco Unified Communications Manager Express. Which command does the engineer use to ensure that the call is reverted to the user after 60 seconds?  R2(config-ephone-dn)#park reservation-group 60  R2(config-ephone-dn)#park-slot timeout 60 limit 2 recall alternate 3002  R2(config-ephone-dn)#park reservation-group 1  R2(config-ephone-dn)#park-slot timeout 30 limit 2 recall alternate 3002 Q38. Refer to the exhibit. A user reports that when they call a specific phone number, no one answers the call, but when they call from a mobile phone, the call is answered. The engineer troubleshooting the issue is expecting the far-end gateway to cut through audio on the 183 Session Progress SIP message. Which SIP Profile configuration element is necessary for the Cisco Unified Communications Manager to send acknowledgement of provisional responses?  Allow Passthrough of Configured Line Device Caller Information must be enabled.  Accept Audio Codec Preferences in Received Offer must be set to On.  On the SIP Profile, the configuration parameter SIP Rel1XX Options must be set to Send PRACK for all 1xx Messages.  Early Offer for G Clear Calls must be enabled.
