Using the 'test_ppg' program, I have the PPG forwarding a response to an SI PUSH
request to an SMSC. I'm trying to understand the details of the response forwarded by
Kannel to the SMSC. I have parsed most of the content of the message, but there are
several response bytes I've been unable to identify. I've used several WAP
PUSH-related standards documents and read through some Kannel source to try and find
how/where the bytes are packed. To be more specific, I've parsed the complete SI
portion of the response. Does anyone have any suggestions on how I can determine the
meaning of the values of the remaining fields? I've replicated some of the data below
with some details removed such as portions of text strings such as URI-related
information and other text strings. I've also removed portions of the IP header fields.
The POS column is the byte number in the output (including TCP/IP header information).
HEX is the hex value of the output character. CHAR is the character representation
('.' shows where the hex value is a non-displayable character), Description is
provided where I've been able to identify a byte meaning.

Since I was able to identify all the fields in the SI document, I thought the
unidentified fields would relate to the push control document, but I've been unable to
make these connections using WAP standards documents and Kannel source/headers,
primarily in the gw and gwlib directories. I think byte numbers 116 through 125 and
152 through 157 will contain the most important information. In particular, I wonder
if these positions represent the values in the "quality-of-service" portion of the
Push Control Document. The SI and Push Control documents I've used are provided below:
