Have you loaded mod_spandsp? This is the replacement for mod_fax.

  I am trying to upgrade from a half year olf FS version to the latest one and face some problems with fax. The fax arrives from the PSTN through an Audiocodes MSBG-1,000 gateway.

With the old version, when I have mod_fax loaded, FS detects that this is a fax call, sends a re-INVITE to the MSBG and enters T.38 mode; this works ok.
With the old version, when mod_fax is unloaded, FS enters T.38 mode without sending re-INVITE, thus the fax fails.

The latest FS version (where mod_fax is not available anymore) works as the second situation above and fax fails. I guess I am missing something in the configs, but I can't find what...

I have in my dialplan:

     <action application="set" data="fax_enable_t38_request=true"/>
      <action application="set" data="fax_enable_t38=true"/>
and I've also tried to add:
    <action application="set" data="execute_on_answer_6=t38_gateway self"/>
but nothing helps. Any idea what I am doing wrong?

                              Thanks! __Yehavi:
