[Freeswitch-users] Freeswitch and OPAL/H323

[Alessandro Russo]

Hi to all,

I am a newbie in Freeswitch (FS).

I have already installed a FS machine,  following the wiki installation
procedure, and I have also added the opal module following this procedure:
http://wiki.freeswitch.org/wiki/Mod_opal

When I running FS

######################################
freeswitch at atest> module_exists mod_opal
API CALL [module_exists(mod_opal)] output:
true
freeswitch at atest>
######################################

I think I'have installed it correctly.
My goal is to provide a conference tool for incoming h323-calls that come
from a cisco call manager: we are behind a Cisco VoIP cloud.
Every time a PSTN phone calls the number 1234-123456 the call manager knows
that the extension 3456 has to be redirected
to 192.168.193.38, that is the IP address of the FS machine, where file
dialplan/default/myconference.xml contains the following lines

######################################
<include>
    <extension name="no_conferences">
      <condition field="destination_number" expression="^3456$">
        <action application="answer"/>
        <action application="info"/>
        <action application="conference" data="$1-${domain_name}@wideband"/>
      </condition>
    </extension>
</include>
######################################

On the other hand, whenever a user of FS calls an local extension (like 1XXX
), what I want is that FS forward this call to the cisco call manager
through opal/h323
therefore I have a file in

######################################
<include>
<extension name="1xxx">
    <condition field="destination_number" expression="^(1\d{3})$">
        <action application="set" data="dialed_extension=$1"/>
        <action application="export" data="dialed_extension=$1"/>
        <action application="set" data="transfer_ringback=$${hold_music}"/>
        <action application="set" data="call_timeout=30"/>
        <action application="set" data="hangup_after_bridge=true"/>
        <action application="set" data="continue_on_fail=true"/>
        <action application="set" data="ringback=$${us-ring}"/>
        <action application="set" data="instant_ringback=true"/>
        <action application="bridge" data="opal/h323:$1 at IP.CALL.MANA.GER"/>
        <action application="answer"/>
        <action application="sleep" data="1000"/>
        <action application="voicemail" data="default
${ip_server_cisco_call_manager} ${dialed_extension}"/>
     </condition>
  </extension>
</include>

but it fails: when a FS user calls 1500, FS returns this message
