  2. Include information regarding the table of selectable codecs by IAX, we discussed on the phone.
  3. Try to keep data together that belongs together.
  4. SIPp test tooling. Nice feature, good discovery. I would like to know if you have experimented with it. It seems rather powerfull.

Think of a way to give results to THALES, for instance Trixbox instances and CD containing the info on this site. Also think about the presentation of the results this Friday, slides/demonstration/etc.

Assignment 1

  1. 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 codec 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.

Discussion Tomorrow

We will discuss the documentation in detail but I think some conclusions should be made more explicit, for example:

VoIP buster 06 numbers are routed through the installed modem-card, because this is cheaper than using VoIPbuster. What does this mean? SIP to land line is possible, what about the reverse? State clearly what the result per step was. Example, you tested H323 clients with a GnuGatekeeper, and communication was possible between H323 <-> H323. But the gatekeeper box should be unchecked. WHAT DOES THIS MEAN?? Gnomemeeting So for these calls you have to check the box. WHICH BOX??

Documentation remarks

Assignment 1

Just a question: Are you sure that Asterisk is always sampling internally to 8000 samples/sec BECAUSE THEN => Maximum recorded frequency ~ 4000 Hz => This is bad for SONAR !!

DUNDi as a routing protocol <-- What happened here

Assignment 2

Editing ZapTel <-- What happened here

Could you make clear that the instructions are to make Case III working. Maybe it is an idea to draw a picture with the configuration where you name the different computers. Then it becomes clear which section of commands should be applied to which computer. Divide theory regarding the possible configurations, and Case III you tried to work out (actually the remark Mr. Achterop made earlier).
