[Freeswitch-users] T38 488 behavior on 1.6.14

[andymurray439 at yahoo.com]

Good evening, 

I noticed Bryan's thread on "BEHAVIOR CHANGE (YES PAY ATTENTION TO THIS IFYOU USE FAXING)" but still having issues. 

I'm running 
FreeSWITCH Version 1.6.14+git~20170130T165359Z~e9cb966d18~64bit (git e9cb966 2017-01-30 16:53:59Z 64bit) 

When a G711 call comes in and then the reinvite occurs from the calling side for T38; FS sends back a "488 Not Acceptable Here" 

I have set this in vars.xml per the suggestion:

<X-PRE-PROCESS cmd="set" data="fax_enable_t38=true"/>

Below is the pastebin of the siptrace:

Below is the dialplan for it:

<action application="answer" /> 
<action application="playback" data="silence_stream://2000"/> 
<action application="set" data="fax_enable_t38=true"/> 
<action application="rxfax" data="/tmp/FAX-${uuid}.tif"/> 
<action application="hangup"/> 

Am I missing anything else to just make this work?

Thanks!
andy....
