Hi all,

I have properly compiled the gsmopen module.

Added the Dialplan

    <extension name="gsmopen">
      <condition field="destination_number" expression="^1002$">
        <action application="bridge" data="gsmopen/interface1/xxxxxxxxx"/>
And the gsm conf file
<configuration name="gsmopen.conf" description="GSMopen Configuration">
<param name="debug" value="8"/>
<param name="dialplan" value="XML"/>
<param name="context" value="default"/>
<param name="hold-music" value="$${moh_uri}"/>
<param name="destination" value="9999"/>
<!-- one entry here per gsmopen interface -->
<interface id="1" name="interface1">
<param name="hold-music" value="$${moh_uri}"/>
<param name="dialplan" value="XML"/>
<param name="context" value="default"/>
<param name="destination" value="5000"/>
<param name="alsacname" value="plughw:1"/>
<param name="alsapname" value="plughw:1"/>
<param name="controldevice_name" value="/dev/ttyACM1"/>
<!-- following interfaces are commented out!
