[asterisk-users] Asterisk Fax Receive - how to get the remoteheader?

[Yves]

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
