hello guys,

i got a problem with read function (http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_read) in dialplan.

<extension name="LangSelInput">
    <condition field="destination_number" expression="^LangSelInput$">
      <action application="set" data="playback_delimiter=!"/>
      <action application="set" data="playback_terminators=#*0123456789"/>
      
      <action inline="true" application="set" data="myLANG="""/>
      <action application="read" data="0 1 ${WELCOME_PR}!${ERR_PR}!${LANG_PROMPT_STRING} myLANG ${LANG_TIMEOUT} "/>
      <action inline="true" application="set" data="LANG_RETRIES=${expr(${LANG_RETRIES}+1)}"/>

      <action application="execute_extension" data="LangSel XML NXIVR"/>
    </condition>
</extension>

   <extension name="LangSel">

      </condition>

      <condition field="destination_number" expression="^LangSel$"/>
      <condition field="${myLANG}" expression="^2$" break="on-true">
         <action application="log" data="INFO ################# EN ################\n"/>
         <action application="set" data="sound_prefix=$${sounds_dir}/en/us/callie"/>
         <action application="set" data="language=en"/>
      </condition>

      <condition field="destination_number" expression="^LangSel$"/>
      <condition field="${myLANG}" expression="^[06789]$" break="on-true">

         <action application="set" data="language=hr"/>
         <action application="set" data="ERR_PR=${NO_LANG_PROMPT}"/>
         <action application="execute_extension" data="LangRetries XML NXIVR"/>
      </condition>

      <condition field="destination_number" expression="^LangSel$"/>
      <condition field="${myLANG}" expression="^.*$" break="on-true">
         <action application="log" data="INFO ################# WRONG LANG SEL ################\n"/>
         <action application="set" data="language=hr"/>
         <action application="set" data="ERR_PR=${WRONG_LANG_PROMPT}"/>
         <action application="execute_extension" data="LangRetries XML NXIVR"/>
      </condition>
   </extension>

when this part of dialplan executes and i enter the DTMF digit immediately on 1st letter, the collected DTMF digits are not consistent... as there is a memory overwrite somewhere ....

you can see myLANG variable holds "1^»@đ" ... of course i dialed 1 as seen in the log (switch_rtp.c:2428 RTP RECV DTMF 1:752).

now, i did some extra testing and found that it happens only when i use a playback_separator to append multiple files to be played....

i checked switch_ivr_read and switch_ivr_collect_digits_count functions but everything seems to be ok there...

can anyone help locating the problem ?

Ps: im running

freeswitch@cxss01> version

FreeSWITCH Version 1.0.6 (svn-exported)

tried with Revision: 17032 before this one but seems to be the same....
