• B. dspfram profile 1 conference Codec G711ulawMaximum conference-participants 8 Telephony- serviceSdspfarm units 4 Sdspfarm tag 4 hwcfb Conference hardwareMax-conference-participants 8
• C. dspfram profile 1 conference Codec G711ulawMaximum sessions 4Maximum conference- participants 8 Telephony-serviceSdspfarm units 1 Sdspfarm tag 1 hwcfb Conference hardware Max- conferences 2
• D. dspfram profile 1 conference Codec G711ulawMaximum sessions 4Maximum conference- participants 8 Telephony-serviceSdspfarm units 1 Sdspfarm tag 1 hwcfb Conference hardware Max- conferences 4

Answer: D

Explanation:
dspfram profile 1 conference--> Configure dspfarm conference parameters
Codec G711ulaw --> Configure codecs that are allowed to participate – by default all codecs are supported Maximum sessions 4 --> Configure maximum number of conferences,here 4
Maximum conference- participants 8 --> Configure max conference participants per conference, here 8 Telephony-service
Sdspfarm units 1 --> Configure maximum number of profiles Sdspfarm tag 1 hwcfb --> Associate profile name and enable Conference hardware --> Enable CME hardware conference
Max- conferences 4 --> maximum number of three-party conferences that are supported simultaneously by the Cisco CallManager Express (Cisco CME) router

NEW QUESTION 8

Refer to Exhibit:

Assume there are no classes of service restrictions and all numbers shown are reachable from this Cisco Unified IP 7965 Phone. Which statement about the dialing key strokes that allow the owner of this phone to reach directory number 2000 is true?

• A. Press the last button on the right hand side of the phone screen.
• B. There is no way to speed dial to directory number 2000 because the speed dial entry is not assigned.
• C. Press 7 on the phone keypad, followed by the Dial soft key.
• D. Press 6 on the phone keypad, followed by the Dial soft key.
• E. Press 5 on the phone keypad, followed by the AbbrDial soft key.

Answer: E

Explanation:
Configure these settings for the speed-dial numbers that you access with abbreviated dialing. When the user configures up to 99 speed-dial entries, part of the speed-dial entries can get assigned to the speed-dial buttons on the IP phone; the remaining speed-dial entries get used for abbreviated dialing. When a user starts dialing digits, the AbbrDial softkey displays on the phone, and the user can access any speed-dial entry by entering the appropriate index (code) for abbreviated dialing.
Configuration for Dialing 5 on the phone keypad, followed by the AbbrDial softkey.

NEW QUESTION 9

A queued call has reached the maximum wait time configured for a Cisco Unified Communications Manager native call queue.
Which statement about what happens to this queued call is true?

• A. Calls are handled according to the Forward Hunt No Answer settings on the Hunt Pilot configuration page.
• B. Calls are handled according to the When Maximum Wait Time Is Met settings on the Hunt Pilot Configuration page.
• C. Calls are handled according to the When Maximum Wait Time Is Met settings in Cisco Unified Communications Manager Service Parameters.
• D. Calls are handled according to the Not Available Hunt Option settings on the Line Group Configuration page.
• E. Calls are handled according to the When Queue Is Full settings on the Hunt Pilot Configuration page.

Answer: B

Explanation:
There are three main scenarios where alternate numbers are used:
When queue is full
When maximum wait time is met
When no hunt members are logged in or registered
When queue is full
Call Queuing allows up to 100 callers to be queued per hunt pilot (the maximum number of callers allowed in queue on a hunt pilot page). Once this limit for new callers been reached on a particular hunt pilot, subsequent calls can be routed to an alternate number. This alternate number can be configured through the Hunt Pilot configuration page (through the “Destination When Queue is Full” settings).
When maximum wait time is met
Each caller can be queued for up to 3600 seconds per hunt pilot (the maximum wait time in queue). Once this limit is reached, that caller is routed to an alternate number. This alternate number can be configured through the Hunt Pilot configuration page (through the “Maximum wait time in queue” settings).
When no hunt members are logged in or registered
In a scenario where none of the members of the hunt pilot are available or registered at the time of the call, hunt pilot configuration provides an alternate number field (through the “When no hunt members are logged in or registered” settings) where calls can be routed. For Call Queuing, a hunt pilot member is considered available if that member has both deactivated do not disturb (DND) and logged into the hunt group. In all other cases, the line member is considered unavailable or logged off.

NEW QUESTION 12

Which codec complexity mode, when deployed on Cisco IOS routers with DSPs using the C5510 chipset,
supports the most G.711 calls per DSP?

• A. Low
• B. Medium
• C. High
• D. Secure
• E. Flex

Answer: E

Explanation:
The flex parameter allows the complexity to automatically adjust to either medium or high complexity depending on the needs of a call. For example, if a call uses the G.711 codec, the C5510 chipset automatically adjusts to the medium-complexity mode. However, if the call uses G.729, the C5510 chipset uses the high complexity mode

NEW QUESTION 13


Which option is the MOS value in the Cisco IOS snippet?

NEW QUESTION 14

What is the maximum one-way delay, in milliseconds, between any two Cisco Unified Communications Manager servers in a non-Session Management Edition cluster over an IP WAN?

• A. 20
• B. 40
• C. 80
• D. 160
• E. 250

Answer: B

Explanation:
The maximum one-way delay between any two Unified CM servers should not exceed 40 msec, or 80 msec round-trip time. Propagation delay between two sites introduces 6 microseconds per kilometer without any other network delays being considered. This equates to a theoretical maximum distance of approximately 3000 km for 20 ms delay or approximately 1860 miles. These distances are provided only as relative guidelines and in reality will be shorter due to other delay incurred within the network.

NEW QUESTION 25

Refer to the exhibit.

Which two statements about the show command output are true? (Choose two.)

• A. T1 0/2/1 terminates Q.921 signaling to a Cisco Unified Communications Manager server.
• B. T1 0/0/0 terminates Q.921 signaling on the gateway.
• C. T1 0/0/0 terminates SIP Signaling to a Cisco Unified Communications Manager server.
• D. T1 0/0/0 terminates Q.931 signaling to a Cisco Unified Communications Manager server.
• E. T1 0/2/1 terminates Q.931 signaling on the gateway.

Answer: BD

Explanation:
As you can see the T1 0/0/0:23 interface is active in layer 1,2(multi frame established) & 3,it means Q.931 signaling terminates at gateway and using backhauled technique q931 messages are going to CUCM server.
But in case of T1 0/2/1 port multi frames are not established in layer 2.So, it’s not configured properly & doesn’t backhauling q931 messages to CUCM
