I have a Hex Dump of ISDN messages and I wonder if Wireshark can be used to decode those messages. Here an example of what I have:

0000  02 01 01 a5                                          
0000  02 01 01 b9                                          
0000  02 01 01 a5

0000  00 01 01 a6                                          
0000  02 01 b8 a6 08 02 80 3e 02 18 03 a9 83 85

0000  00 01 a6 be 08 02 00 3e 0f                         
0000  00 01 01 a8                                          
0000  00 01 a8 be 08 02 00 3e 45 08 02 8a 90            
0000  00 01 01 aa

0000  00 01 01 ac                                          
0000  02 01 01 ad                                          
0000  02 01 01 c1                                          
0000  02 01 01 ad                                          
0000  02 01 01 c1

I've try to use text2cap command but wireshark couldn't decode the ISDN messages. The command used was text2pcap.exe -s 273,819,1 TXT.file CAP.file

Is there a way to make it work ?

Thank you

Marcelo

You need to specify a data link type of 203 (see pcap/bpf.h). Try text2pcap -l 203 file.txt file.pcap.
