Hi Spencer, I use this (gatewaying via a Mitel 3300 but there is no reason why it would not work for FreeTDM, just change the bridge at the end). <action application="set" data="absolute_codec_string=PCMU"/> <action application="set" data="fax_enable_t38=true"/> <action application="set" data="sip_execute_on_image=t38_gateway self nocng"/> <action application="bridge" data="sofia/gateway/10.10.0.2/$1"/> Hope this helps if a bit late.

Hello, I'm trying to use Freeswitch as a SIP to TDM gateway. I'd like to use t38_gateway to detect fax tones and send a ReINVITE to t38.
Have a very minimal config with one profile that simply relays to FreeTDM
My dialplan is: <include> <context name="sip">
<extension name="dial-trunk"> <condition field="destination_number" expression="^(.*)$"> <action application="set" data="fax_enable_t38=true"/> <action application="set" data="fax_enable_t38_request=true"/> <action application="set" data="execute_on_answer=t38_gateway self"/> <action application="bridge" data="freetdm/1/a/$1"/> </condition> </extension>
</context> </include>
The problem is a media bug is created on the channel but almost immediately destroyed so fax tones are never detected.

Thanks for any assistance, Spencer
