[asterisk-users] Asterisk and spandsp fax problem

[Fulajtár Pál]

Hi,

  I am recently updated my asterisk 1.4.1 to 1.6.2.6 because of fax
service. I have installed spandsp 0.0.5, then 0.0.6 pre 17 as well
because to have support. app_fax is available in menuselect and loaded
into my asterisk. The upgrade went without any problems.

ast*CLI> module show like fax
Module                         Description

app_fax.so                     Simple FAX Application                   0

But I cannot use Zoiper Business SIP fax service with, I always get
error message regardless I want to send fax to a PSTN or I want to
ending it locally on Asterisk.

Dou you have any suggestion what could cause this problem. All of other
