Hi,
I haven't found anything definitive however I expect the TSI that is
sent during initial fax call establishment is stored by the receiving
terminal, see pages 28 & 29 of the English version of the document at
https://www.itu.int/rec/T-REC-T.30-200509-I/en , I expect the header,
which will include the TSI, is all part of the image (Tagline in
HylaFAX) and not stored separately on the receiving terminal.
Cheers,
Larry.

Hi,
thanks for your answer. Unfortunately this is, what I already know. I
was wondering, why it is possible to set ID and Header for an
outgoing fax (which will then in turn
be inserted via asterisk on top of the transferred "image") , while
it seems to not be possible to get the Header from a received fax
(only the id), although it is present in the faxdocument.
The ID is also present in the faxdocument and there does a
Faxopt(remotestationid) exist... so I thought, this info must be
transferred not only binary within the "image", but
also within the "meta-data" / protocol-data of the fax (within the
TSI).... otherwise asterisk must do some kind of ocr to get the ID,
what it definitely does not...
btw... when using sendfax, asterisk inserts the date, the id, the
header and the pagenum on top of each faxpage... someone knows how to
modify some settings like font, position, and so on?
thanks,
yves

It doesn't appear that a received header is available unless it is
written into the 'headerinfo' variable after it is received, I
haven't checked for this.
From my days working with fax machines, the header could be inserted
in the line the TSI is on or in the image being transmitted, if you
receive a fax that has been sent to you with the latter set, then
the 'headerinfo' will not be of any use. Perhaps someone with more
knowledge may be able to explain this better.
A quick Google search for 'fax header outside of tsi' will provide a
list of manuals, here's one -

Expand the line for
To specify the position of Header Position printed on a sent
fax ([Header Position])

Hi,
I am using asterisk 11.8 in combination with spandsp to send and
receive T38 Faxes. All works fine, but I do not know
how to get the remoteheader from the fax I receive.
When I send a fax, there are Faxopts to set the localstationid and
the headerinfo, but for receiving, there seems to only exist
the Faxopts remotestationid
but for sure on any fax I receive there is a remoteheaderinfo
besides the remotestationid... it is on the tiff-file, but I need this
info in a channel-variable...
Does anybody know how to get the remoteheaderinfo for a received fax?
thanks
yves
