• 0.01 Wiki is een hele mooie oplossing, zorg wel voor een duidelijke structuur. Bijvoorbeeld als volgt:
  • literatuur
    • Codecs
    • Protocols
    • Software tooling
    • etc.
  • experiment VoipBuster
    • experiment set up
    • result
    • conclusions indien van toepassing.
  • experiment Dundi blabla
    • experiment set up
    • result
    • conclusions indien van toepassing.
  • analysis of this and that
    • experiment set up
    • result
    • conclusions indien van toepassing.
• 0.02 Include information regarding the table of selectable codecs by IAX, we discussed on the phone.
• 0.03 Try to keep data together that belongs together.
• 0.04 SIPp test tooling. Nice feature, good discovery. I would like to know if you have experimented with it. It seems rather powerfull.
• 0.05 Start thinking about the way you will present the features when I am at the university.

Assignment 1

• 1.01 Article: Voice-only with different codecs. Not clear is which codec is used where and conclusion is missing

Article: Voice only analysis. Not clear which coded is used. Which values are expected and what the results are; Bandwidth is xx,x kbit/s which is less than the 123 kbit/s

for the g71234 codec. Conclusion > Parameter "Bandwidth = low" in IAX.conf selects the optimal codec

• 1.02 Article: Voice and video analysis. To be able to answer this question you need my measurements, I did not provide yet. Could the following :
• 1.03 Be a little more specific. Now you have: IAX2IAX2 is the Inter-Asterisk eXchange protocol. This is used to transport the calls between Asterisk PBX stations. Thus

comparible with SIP and the protocol used is selected on criteria x,y,z and the selection can be found in a table made by the PBX at startup etc. etc. etc. ???

• 1.04
• 1.05 Describe how to setup PBX-VMware. Tips and tricks etc. Maybe it is just sufficient to grab your file and load it to VMWare.

Assignment 2

• 2.01 Keep up the spirit with this assignment.
• 2.02 Hebben jullie VoipBuster gedaan op Trixbox 2.0 ipv 1.2.3. Zo ja wat zijn de verschillen, ik wil graag kunnen werken op 1.2.3. Tenzij alles beter is op 2.0
• 2.03 Article: Conference call. As mentioned during phone call, conferencing hosted by the pbx using video should be investigated.
• 2.04
• 2.05
