Hi,
I have implemented the solution for tone detection in wiki, and also answer
the channel before detecting the tone:
<condition field="destination_number" expression="^(055138419992)$">
<action application="answer"/>
<action application="tone_detect" data="fax 1100 r +15000 transfer fax
XML default"/>
<extension name="fax">
<condition field="destination_number" expression="^fax$">
<action application="answer" />
<action application="sleep" data="1000"/>
<action application="rxfax"
data="/usr/local/freeswitch/storage/fax/${caller_id_number}-${strftime(%Y-%m-%d-%H-%M-%S)}.tiff"/>
<action application="set" data="fax_mode=recv"/>
<action application="hangup"/>
</condition>
</extension>
But FS cannot recognize the tone, and therefore cannot move to fax
extension. Below are the error in FS:
2009-10-12 10:57:16.702287 [NOTICE] switch_channel.c:602 New Channel

I think the trouble here is that you don't have anything else in the dialplan after the tone_detect. The tone_detect app is non-block, which means that it doesn't sit there and wait for a tone. If you want the dialplan to sit and wait then do a sleep app after your tone_detect. The other question I would have is this: what happens if the incoming call is not a fax? What do you want to do then?

This is what I have in my dialplan and the fax is detected
beautifully. Note that in my case, extension 1000 will ring for a
second or two before the fax is detected. So in your example, the fax
does not have time to be detected, the dialplan exists and the call is
hungup.
When the fax is detected, the call is transferred to the receivefax
extension in context features. The extension 1000 does not have to be
answered for the transfer to occur.
<extension name="Local_1000s">
<condition field="destination_number" expression="^(10[01][0-9])$">
<action application="set" data="dialed_extension=$1"/>
<action application="export" data="dialed_extension=$1"/>
<action application="set" data="ringback=${au-ring}"/>
<action application="tone_detect" data="fax 1100 r +5000
transfer 'receivefax XML features' 1" />
<action application="set" data="hangup_after_bridge=true"/>
<action application="set" data="continue_on_fail=true"/>
<action application="bridge" data="user/${dialed_extension}@${domain}"/>
<action application="answer"/>
<action application="sleep" data="1000"/>
<action application="voicemail" data="default ${domain_name}
${dialed_extension}"/>
</condition>
</extension>
and in the features context I have
<extension name="receivefax">
<condition field="destination_number" expression="^receivefax$">
<action application="answer" />
<action application="playback" data="silence_stream://2000"/>
<action application="rxfax"
data="//usr//local//freeswitch//storage//${caller_id_number}-${uuid}.rxfax.tiff"/>
<action application="system"
data="/usr/local/freeswitch/scripts/emailfax.sh
/usr/local/freeswitch/storage/${caller_id_number}-${uuid}.rxfax.tiff"/>
<action application="hangup"/>
</condition>
</extension>
