Hi Philippe
 
I've attached to sample captures. As well as the decoding using tshark.exe.  The text files containing the dissected data were generated with the following command
 
tshark -r 04-01.16-29-UM.ppp -V > 04-01.16-29-UM.txt
tshark -r SMS_originator-UM.ppp -V > SMS_originator-UM.txt
 
The protocol column doesn't get update correctly either although I'm pretty that it was displayed as SIP/is637 when I ran the script last week.

Hello Peter,

Your dissector is loaded correctly by Wireshark,
but it is difficult without packets capture to see what is going wrong.
Could you send us a capture example of your SIP protocol ?

Regards
Philippe

Subject: [Wireshark-dev] is-637 dissector

Hi
 
I've written a custom dissector enhance SIP message parsing.  The dissector works properly when invoked from tshark.exe
however the is-637 decoding doesn't work from with the GUI version of wireshark.  Is there anything special that I need to do ?
 
 
Thanks
