In this tutorial I will show you how to configure ivr_demo and Voice mail in German Language.You can configure even your dial plan.
1) Basic Setup
Install German sounds from freeswitch-sounds-de-at-ute-8000-0.0.1.tar.gz from http://freeswitch.xpirio.com/
extract in /opt/freeswitch/sounds.
In directory “opt/freeswitch/sounds/de/at/ute/” create folder ivr and copy “8000” folder from “opt/freeswitch/sounds/de/at/ute/ivr_not_ok” . This step is important to enable ivr in German.
Install freeswitch-lang-de from synaptic if not installed.
Add ” <load module=”mod_say_de” /> ” in /conf/autoconf/module.conf.xml under ” <!– Say –> ” section.
In freeswitch.xml add ” <X-PRE-PROCESS cmd=”include” data=”lang/de/*.xml”/> ”
<section name="phrases" description="Speech Phrase Management">
<macros>
<X-PRE-PROCESS cmd="include" data="lang/de/*.xml"/>
<X-PRE-PROCESS cmd="include" data="lang/en/*.xml"/>
</macros>
</section>
modify sound-path in /conf/lang/de/de.xml to “$${sounds_dir}/de/at/ute” .
<include>
<language name="de" sound-path="$${sounds_dir}/de/at/ute" tts-engine="cepstral" tts-voice="david">
<X-PRE-PROCESS cmd="include" data="demo/*.xml"/>
<!--voicemail_de_tts is purely implemented with tts, we need a files based implementation too --><X-PRE-PROCESS cmd=”include” data=”vm/tts.xml”/>
</language>
</include>
2) ivr_demo in German.
goto /conf/dialplan/default.xml .search for “ivr_demo” . when you call on 5000 ,you will hear ivr in english language. To configure it in German add following line under “condition” section in “ivr_demo” extension.
<action application=”set” data=”default_language=de”/>
For example.
<!-- a sample IVR -->
<extension name="ivr_demo">
<condition field="destination_number" expression="^5000$">
<action application="set" data="default_language=de"/>
<action application="answer"/>
<action application="sleep" data="2000"/>
<action application="ivr" data="demo_ivr"/>
</condition>
</extension>
copy /opt/freeswitch/conf/lang/en/demo/demo-ivr.xml to /opt/freeswitch/conf/lang/de/demo/ .
and modify /opt/freeswitch/conf/lang/de/de.xml to
<include>
<language name="de" sound-path="$${sounds_dir}/de/at/ute" tts-engine="cepstral" tts-voice="david">
<X-PRE-PROCESS cmd="include" data="demo/*.xml"/>
<!--voicemail_de_tts is purely implemented with tts, we need a files based implementation too -->
<X-PRE-PROCESS cmd="include" data="vm/tts.xml"/>
</language>
</include>IF you don’t follow above step you will get following error when you call on 5000
[ERR] switch_ivr_play_say.c:150 Can't find macro demo_ivr_main_menu.[ERR] switch_ivr_play_say.c:150 Can’t find macro demo_ivr_main_menu_short
etc…
We are Done !!
3) Voicemail in German.
Open /conf/dialplan/default.xml . Search <extension name=”vmain”> .
Add <action application=”set” data=”default_language=de”/>
For Example.
<!-- voicemail main extension -->
<extension name="vmain">
<condition field="destination_number" expression="^vmain$|^4000$|^\*98$">
<action application="set" data="default_language=de"/>
<action application="answer"/>
<action application="sleep" data="1000"/>
<action application="voicemail" data="check default ${domain_name}"/>
</condition>
</extension>
Call 4000 .
if you run into following error
" [ERR] switch_core_speech.c:61 Invalid speech module [cepstral]!
[ERR] switch_ivr_play_say.c:2136 Invalid TTS module!
[ERR] switch_core_speech.c:61 Invalid speech module [cepstral]!
[ERR] switch_ivr_play_say.c:2136 Invalid TTS module!
[ERR] switch_core_speech.c:61 Invalid speech module [cepstral]!
[ERR] switch_ivr_play_say.c:2136 Invalid TTS module!
"
You need to install cepstral Or you can follow the following trick.
copy /opt/freeswitch/conf/lang/en/vm/sounds.xml to /opt/freeswitch/conf/lang/de/vm/ .
modify /opt/freeswitch/conf/lang/de/de.xml to as follow.
<include>
<language name="de" sound-path="$${sounds_dir}/de/at/ute" tts-engine="cepstral" tts-voice="david">
<X-PRE-PROCESS cmd="include" data="demo/demo.xml"/>
<!--voicemail_de_tts is purely implemented with tts, we need a files based implementation too -->
<!--
<X-PRE-PROCESS cmd="include" data="vm/tts.xml"/>
-->
<X-PRE-PROCESS cmd="include" data="vm/sounds.xml"/>
</language>
</include>
Call 4000 .
We are done!
3) custom dialplan in German.
In pervious tutorial we created simple dialplan which pronouns some digits. dialplan was as follow.
<extension name="mydemo">
<condition field="destination_number" expression="^5343$">
<action application="answer"/>
<action application="say" data="en number pronounced 12345"/>
</condition>
</extension>to pronouns digit in German you need to just add following line.
<extension name="mydemo">
<condition field="destination_number" expression="^5343$">
<action application="set" data="default_language=de"/>
<action application="answer"/>
<action application="say" data="en number pronounced 12345"/>
</condition>
</extension>
We are done!!

The error ‘invalid tts module cepstral’ still remains after installing cepstral and doing your trick for german voicemail. All other announcements are working correctly after modifying it!
If you have a solution for this, please help me
If you have sounds then you do not requires cepstral. You can disable it.

I have just started working on FreeSWITCH, to create an IVR. But stuck with its complex configuration as I am a newbie. Please help me to understand the configuration, if possible.
Hi Sanjay,
I am having the same problem here. I am stuck in the configuration of my digium card. I can’t find a dialplan to connect the card to an e1 line. I hope our friend junedmunshi will help us.
