</configuration>

when i call the pstn phone from a ip phone,if the pstn call hangup first,the ip phone will hear the busy tone,but the system does not handle the busytone ,the channel does not erase. so i have to add 
<action application="tone_detect" data="busy 450,340 w +25000 hangup 'normal_clearing' 3"/> in the dialplan.and it works.the channel erased.

but in the conference case,pstn phone call in,hangup. all participants hear the tone,"do ~,do~~".freeswitch doest handle it.
so i change the conference dialplan.


<extension name="incoming-fxo-channel-1"> 
<condition field="source" expression="mod_openzap">
<action application="tone_detect" data="busy 450,340 w +25000 hangup 'normal_clearing' 3"/> 
<action application="bridge" data="sofia/maqian/6789 at njpbx.vicp.net"/>
     </condition> 
   </extension>

restart freeswitch,try again,freeswitch not handle the hangup tone still,all participants hear the tone.
how to solve it?could some one help me ???
thx!
