Wireshark · Ethereal-dev: Re: [Ethereal-dev] T.38 nonexisting HDLC commands

[Alejandro Vaquero <alejandrovaquero@xxxxxxxxx>]

I think  it is related to the reassemble of t30. Please provide the file 
to take a look. Also notate that the reasemble only works for the first 
two Items in a t38 packet, so if there are more than two items, that can 
lead to a miss reassemble packet.
