hi,
finally got the fax report to work, heres more info for those willing to
do it without using any ESL stuff
first in the originate command include the below (change the script path
and name to whatever u use, this will be called when the fax session is
over):
api_hangup_hook=lua /home/pi/hangup.lua
in your hangup.lua script u can get the spandsp variables as below:
fax_success = env:getHeader("fax_success")
fax_result_code = env:getHeader("fax_result_code")
fax_result_text = env:getHeader("fax_result_text")
these i just pass them to a python script where i send the mail to
sender with a properly formatted fax report letting him know if it was
successful or not
Regards,
Bipin
