I am facing a bizarre behavior while trying to send fax from zoiper to freeswitch.
First, i tried to use the dialplan example as shown in documentation page.
<extension name="fax_receive">
<condition field="destination_number" expression="^9978$">
<action application="answer" />
<action application="playback" data="silence_stream://2000"/>
<action application="set" data="fax_enable_t38_request=true"/>
<action application="set" data="fax_enable_t38=true"/>
<action application="rxfax" data="/tmp/FAX-${uuid}.tif"/>
<action application="hangup"/>
</condition>
</extension>
But this resulted in "488 Not Acceptable Here" even though i have set fax_enable_t38 in vars.xml
Logs.
Second, But i remove few lines from dialplan.
<extension name="fax_receive">
<condition field="destination_number" expression="^9978$">
<action application="answer" />
<action application="rxfax" data="/tmp/FAX-${uuid}.tif"/>
<action application="hangup"/>
</condition>
</extension>
Everything seems to work perfectly.
Third. When i insert a small lua script after answer in above dialplan it again fails with 488.
<extension name="fax_receive">
<condition field="destination_number" expression="^9978$">
<action application="answer" />
<action application="lua" data="jack.lua"/>
<action application="rxfax" data="/tmp/FAX-${uuid}.tif"/>
<action application="hangup"/>
</condition>
</extension>
I just want to run a small lua script before i call rxfax application.
Any help would be much appreciated.
Best Regards.
