An engineer is troubleshooting a video audio issue where the video endpoint logs are showing this error message.
Which two actions must the engineer take to fix the issue? (Choose two.)
- A . Assign the transcoder to the MRGL, which is in turn assigned to the MRG; apply the MRG to the endpoint device pool of the video.
- B . Assign the transcoder to the MRG, which is in turn assigned to the MRGL; apply the MRGL directly to the endpoint of the video.
- C . Assign the transcoder to the MRGL, which is in turn assigned to the MRG; apply the MRG directly to the endpoint of the video.
- D . Assign the transcoder to the MRG, which is in turn assigned to the MRGL; apply the MRGL to the video’s endpoint device pool.
- E . Assign the transcoder directly to the endpoint of the video.
An engineer is troubleshooting an issue where aliases that contain an identity “@abc.com” are unable to register with an endpoint due to an entry in the registration restriction configuration in Expressway-E.
Where is the alias being blocked in Expressway-E?
- A . regex list
- B . hunt list
- C . black list
- D . allow list
Which two statements about Cisco Unified CM location bandwidth deduction are true? (Choose two.)
- A . If a call uses G.711, Cisco Unified Communications Manager subtracts 64k.
- B . If a call uses G.711, Cisco Unified Communications Manager subtracts 80k.
- C . If a call uses G.723, Cisco Unified Communications Manager subtracts 16k.
- D . If a call uses G.729, Cisco Unified Communications Manager subtracts 16k.
- E . If a call uses G.729, Cisco Unified Communications Manager subtracts 24k.
Refer to the exhibit.
Inbound calls via a SIP trunk to the Cisco IP phones that are registered on Cisco Unified Communications Manager are failing.
Based on the Cisco CallManager service trace, which action should you take to fix the issue?
- A . Add xyz.com in the Organization Top Level Domain field on Cisco Unified Communications Manager.
- B . Set the Incoming Transport Type to TLS on the SIP trunk security profile that is assigned to the SIP trunk.
- C . Check whether the calling search space for incoming calls on the SIP trunk has access to the partition of the Cisco IP phone that is being called.
- D . Add vcs.abc.org in the Organization Top Level Domain field on Cisco Unified Communications Manager.
Refer to the exhibit.
In this CUCM dial-plan, a localized translation pattern 9.1[2-9]XX[2-9]XXXXXX is configured in the Calling Search Space named LongDistance_CSS. This Translation Pattern is used to globalize the User’s dialed digits followed by matching a/+! Route Pattern as seen in the Exhibit. Users with Devices/Lines assigned to the LongDistance_CSS are reporting their calls are not proceeding until after the inter-digit timeout of 15 seconds. For example, after dialing digits 915555678309 the user does not hear ringback until after 15 seconds.
What two reasons could lead to this inter-digit timeout condition? (Choose two.)
- A . Route Pattern Call Classification set to OffNet.
- B . Route Pattern does not have “Allow Overlap Sending” checked
- C . Translation Pattern has “Provide Outside Dial Tone” checked
- D . Translation Pattern does not have “Urgent Priority” checked
- E . Route Pattern does not have “Urgent Priority” checked
A company has a headquarters site and a remote site. Cisco Unified Communications Manager acts as a DHCP server. Both sites use their local voice gateways for PSTN calls. At the headquarters site, the PSTN prefix is 9, and the emergency number is 911. At the remote site, the PSTN prefix is 0, and the emergency number is 112.
Here are the deployment policies for roaming devices:
– Softphones can roam between two sites.
– A roaming softphone uses the local gateway for all PSTN calls.
– The user keeps home dial habits on a roaming softphone, with the exception of the emergency number.
When a headquarters user uses a softphone at the remote site, the administrator notices that the PSTN calls are still going via voice gateway in the headquarters. The administrator enabled Device Mobility in the system parameters and on all phones.
What are the next two components that the administrator must check, according to the flow of Device Mobility operation? (Choose two.)
- A . IP address of the softphone
- B . Cisco Unified CM Group
- C . Device Mobility Info
- D . Physical Location
- E . Device Mobility Group
Which command is used to check if an MGCP gateway is currently registered with Cisco CallManager?
- A . Router# show ccm-manager gateway
- B . Router# show mgcp ccm-manager
- C . Router# show ccm-manager
- D . Router# show ccm manager
If a user receives a reorder tome after dialing a number, the Cisco Unified Communications Manager
bandwidth allocation for the location of one of the call end devices may have been exceeded.
Which option is true?
- A . If the call is using G.711, Cisco Unified CM subtracts 64k.
If the call is using G.723, Cisco Unified CM subtracts 16k.
If the call is using G.729, Cisco Unified CM subtracts 8k. - B . If the call is using G.711, Cisco Unified CM subtracts 80k.
If the call is using G.723, Cisco Unified CM subtracts 24k.
If the call is using G.729, Cisco Unified CM subtracts 24k. - C . If the call is using G.711, Cisco Unified CM subtracts 80k.
If the call is using G.723, Cisco Unified CM subtracts 24k.
If the call is using G.729, Cisco Unified CM subtracts 16k. - D . If the call is using G.711, Cisco Unified CM subtracts 64k.
If the call is using G.723, Cisco Unified CM subtracts 24k.
If the call is using G.729, Cisco Unified CM subtracts 8k.
You observe that EMCC restriction on the cluster fails when a user with a different profile logs in to another cluster.
Which action can you take to correct the problem?
- A . Enable logical partitioning.
- B . Set SIP session timers to 0.
- C . Set SIP session timers to 3800.
- D . Configure the regions in Cisco Unified Communications Manager to allow EMCC.
An engineer is configuring a new conference resource on a Cisco 2911 ISR router. The router has a single PVDM3-32 and one PRI with 23 voice channels. When the engineer configured the conference profile on the router, the following message is received.
Vr-2911-east(config)#dspfarm profile 10 conferenceDspfarm profile 10 :: No resource, check voice card or dspfarm service is not configured
Which configuration should the engineer add before adding the conference bridge profile?
- A . voice-card 0 dsp services dspfarm dspfarm
- B . voice-card 0 codec complexity medium dsp services dspfarm
- C . voice-card 0 codec complexity flex dsp services dspfarm
- D . voice-card 0 dsp tdm pooling dspfarm
