asterisk users - Nov 2008 - asterisk 1.2 and Dial with LIMIT_WARNING_FILE

Hi fellows..
I have 2 asterisk servers in which the following line

exten =>  _09049.,111,SetVar(LIMIT_PLAYAUDIO_CALLER=YES)
exten =>  _09049.,112,SetVar(LIMIT_WARNING_FILE=beep)
exten =>  _09049.,113,Dial(${TYPE}${DESTINO}|30|L(30000:10000))


works OK on my Asterisk 1.2.9, it plays the beep 10 seconds before the
end of the call.


doesn't work on my Asterisk 1.2.13, it hungs 10 seconds before the end
of the call, just when it has to beep


both of them have the same chan_ss7 and the beep.gsm in the correct place.


Do you have any idea of what is happening?

Thanks in advance..
