Hi,
One of
the limitations to the current SIGCOMP decoder is that all instruction codes are
not implemented, it does work on some sample
captures I have and also on some of the sample stress
tests.
If the
instruction isn't implemented like SIGCOMP_INSTR_SORT_ASCENDING you should get a
printout in the UDVM execution trace
saying
"Execution of this instruction is NOT implemented"(sigcomp-udvm.c in dir
../epan).
The included frame shows decompressing text(not a SIP message). In
the preferences you can set very detailed dissection of the
decompression
process to see what goes wrong. If you want to send me a sample
trace I can have a look to try to find out whats going
wrong.
Best
regards
Anders
hi
all,
i'm compressing a
sip message by sigcomp mechanism.
i want to check
wether the sigcomp message formed is proper.
i'm using Ethereal
Version 0.10.11 for the purpose.
however ethereal
is not able to decode the sigcomp message.
i would like to
know if there is any freely available sigcomp tool to test the
same.
is the ethereal
implementation of sigcomp fully compliant to rfcs 3320 and
3321?
if not, what are
the limitations?
is there a test
program for ethereal's sigcomp module? it could serve as a reference for
me.
thnx in
advance.
