  Item 1 the choice A: Low complexity is the correct answer not D:
  
  Select a lower codec complexity to support the greatest number of voice channels, provided that the lower complexity is compatible with the particular codecs in use.

  So the answer of nagamin90q.vce is the correct one

• Sahil from Kuwait - Mar 18 2012, 6:51 PM Report Spam

  Passed today with score of 872. 90% questions are same. However, 10-12 questions were different.
  
  1. What is the min for delay, jitter and packetloss which will not affect the performance of voice.
  jitter - ???
  delay - 0-150ms
  packetloss - 1% packet loss.
  
  2. select the 4 dhcp options for dhcp configuration
  1. ip dhcp pool cisco
  2. network a.b.c.d 255.255.255.0
  3. default-router xyz
  4. some-thing some-thing ip xyz.
  
  - All the best.

  Which codec complexity type will offer the greatest number of voice channels, provided that the complexity type is compatible with the particular codecs that are in use?
  A. low complexity
  B. medium complexity
  C. high complexity
  D. flex complexity
  
  I believe the correct answer here should be D. There are 4 codec complexity types; medium, high, flex and secure.There is no low complexity type. Flex offers the greatest number of voice channels because it allows over subscription.

  Passed today with 949/1000 90Q are still valid
  But confused in few questions of drag and drop and multiple select.
  In VOIP drag and drop for dial peer match not port option default dial peer must select.
  
  For no of voice calls question
  
  20 Bytes is voice payload
  2 Bytes compressed header
  8 Bytes for framerelay
  
  BW per call=(Voice payload + L4+ L3+L2)*Packet ratio*8
  BW per call=(20+2+8)*50*8=12000=12KB/S
  No of call for 64K BW=64/12=5 Calls
  
  Q: Voice packets are arriving at a destination with a variance of between 20 and 50 ms . if the jitter buffer has a capacity of 30 ms, What is the impact of audio at receiving IP Phone?
  
  In dump Ans: B
  
  But in paper B options wan not there.

  Passed Friday 910/1000 this dump and 90q is valid,

  Today (24th Feb 2012), I clear CVoice v8.0 exam with 910/1000.
  
  I use for exam preparation: Voicetut, Exam-collection, Actual Test, CVoice 8.0 Book and Voice bootcamp.
  
  Special Thanks to, Voicetut team; Exam collection and all guys here wrote the Comments.

  A lower codec complexity supports the greatest number of voice channels, if the lower complexity is compatible with the particular codecs in use.
  
  High complexity: This option supports any high-complexity codec or a combination of high- and lower-complexity codecs.
  
  Medium complexity: This option supports any medium-complexity codec or a combination of medium- and low-complexity codecs. It offers the greatest number of voice channels, if the lower complexity is compatible with the particular codecs in use. All medium-complexity codecs can also be run in high-complexity mode, but fewer (usually about half) of the channels are available per DSP.
  
  Flex: In this option, more voice channels can be connected (or configured in the case of DS0 groups and PRI groups) to the module than the DSPs can accommodate. If all voice channels should go active simultaneously, the DSPs become oversubscribed, and calls that are unable to allocate a DSP resource fail to connect. This is the default setting.

  That dump is based on voicetut.com forum on a post from mans cisco, taurus and other.
  
  Dump 90q from nagamin also contains Quest 1, and correct answer is low compl (A), but nobody discussed about it, and some time later on voicetut came another answer - flex compl. I'm comfused too.
