[Freeswitch-users] gsm file record/playback

[Miroslav Mostic]

Hi everyone!

I am probably missing something very basic, but I have problems with simple
file record and playback in gsm file format.

I have just installed 1.0 release system and I changed only default dialplan
with following two extensions:

<extension name="gsm_record">
      <condition field="destination_number" expression="^9991$">
        <action application="answer"/>
        <action application="record" data="/tmp/rec.gsm"/>
      </condition>
    </extension>
    <extension name="gsm_playback">
      <condition field="destination_number" expression="^9992$">
        <action application="answer"/>
        <action application="playback" data="/tmp/rec.gsm"/>
      </condition>
    </extension>

 When I place call to 9991extension I see INFO message about opening
/tmp/rec.gsm, no error messages and when I hangup I can see that file
/tmp/rec.gsm exists. However when I try to play this file using 9992
extension the only thing I can hear is noise.

When I just change name to /tmp/rec.wav in both extensions everything is
working fine.

What am I missing?

Many regards,

Miroslav
