Hi all, 
I have a text file which contains a MTP3 frames MTP3. To convert this
file into a pcap file and to decode it thereafter by Wireshark, I used:
"text2pcap -l 141 inputFile.txt outputFile.pcap". 
But now I wish to decode a file which contains both of IP and MTP3
frames. How can I do that. 
Thanks for any Idea
