[Freeswitch-users] Logical AND + NOT

[Dmitriy Shumaev]

 Hi

I want to record all sessions, except calls to group numbers and to IVR. So I need something like:
 <!-- eavesdrop -->
 <extension name="record_3..16_digits" continue="true">
   <condition field="${is_already_recording}" expression="^$"/>
   <condition field="destination_number" expression!="^(400)$"/>  <!--NOT EQUAL--><!-- IVR -->
   <condition field="destination_number" expression!="^(399)$"/>  <!--NOT EQUAL--><!-- Group number -->
   <condition field="destination_number" expression="^(\d{3,16})$">
 <action application="set" data="RECORD_TITLE=Recording ${caller_id_name} ${caller_id_number} to ${destination_number} at ${strftime(%Y-%m-%d %H:%M)}"/>
 <action application="set" data="RECORD_STEREO=true"/>
 <action application="export" data="ignore_early_media=true"/>
 <action application="set" data="media_bug_answer_req=true"/>
 <action application="record_session" data="$${base_dir}/recordings/archive/${strftime(%Y-%m-%d-%H-%M-%S)}_${caller_id_name}_${caller_id_number}_2_${destination_number}.mp3"/>
 <action application="export" data="is_already_recording=true"/>
   </condition>
 </extension>
.  But the syntax of condition  does not allow the operator " not equal" or "!=". What should I do?
