[Asterisk-Dev] packet Dump please

[Derek Smithies]

Hi,
 6 days ago, I wrote to this list:

Since then, no response on this list, or offline.

=============================

Yes, I am guilty of reposting, which is 
(from Eric S. Raymond http://www.catb.org/~esr/faqs/smart-questions.html)
in general, a bad idea. I apologise for this repost, but wonder if my
original request has been "forgotten"

Let me explain my problem a bit more. I am writing the iax library in C++
with the pwlib class library. There are some areas of confusion with just
reading the source iax2 code as to how things happen. A packet dump will
clear these areas up. Using the pwlib class library will provide jitter
buffer, a tidy interface to h323 protocol, access to the quicknet
hardware, and provide a cross platform result (Linux, BSD, Mac, Windows)

I don't have any asterisk hardware here, and am not in a position to setup
two iax clients to get a packet dump. And even if I did this, I would not
get some of the more interesting packets. Such as packets containing 
encrypted data, or trunked packets.

I would really really appreciate any packet dump - this would aid the work  immensely.  

I expect to see my code released open source, along with any documents  written.


========================

Surely, someone can help ? 
With an existing asterisk setup, it cannot be that hard to do, is it ?

I don't need an explanation of what happened in the call. I just want the 
dump. There is sufficient information in the packet dump, and the source 
code, to work out what happend.

Thanks in advance,
 Derek.


P.S. Reposting is my idea, not Frank's. If you want to flame someone, 
flame me. Please do not flame Frank.
