I'm ready to tackle creating a multi-level IVR. From what I have seen in the wiki, what I have to do is to create a separate wav file for each prompt in some other software and then create an XML file to organize the logic around pointers to the wav files and terminating in the requited actions.

Well you could use Text To Speech , if you don't want to create prompts. 2008/9/25 Jim Flowers <jflowers@ezo.net>

You seem to understand the basics around creating the IVR. An easy way to make the recordings is to use FreeSWITCH. Add the following to your dialplan at /usr/local/freeswitch/conf/dialplan/default.xml. Then call extension 8335 or 8336 and say what you want for the recording and then end the call. There are two extensions so you can record more than one wav file without overwriting it. After you made a recording rename the wav file to something logical for your IVR. Then you are ready to use the wav file in the IVR. <extension name="8335"> <condition field="destination_number" expression="8335"> <action application="answer"/> <!--default terminator is *. Keyword 'none' disables on-key termination /--> <action application="set" data="playback_terminators=#"/> <action application="record" data="/usr/local/freeswitch/recordings/8335.wav 180 200"/> </condition> </extension> <extension name="8336"> <condition field="destination_number" expression="8336"> <action application="answer"/> <!--default terminator is *. Keyword 'none' disables on-key termination /--> <action application="set" data="playback_terminators=#"/> <action application="record" data="/usr/local/freeswitch/recordings/8336.wav 180 200"/> </condition> </extension> --- On Thu, 9/25/08, Jim Flowers <jflowers@ezo.net> wrote:

Right now there are two primary ways to build IVRs in FS: scripting language or XML files. There isn't any way that I'm aware of (yet) to simplify the process, such as a GUI-ish front-end software for building IVRs. Personally, I've just been using the combination of XML files. I know that Brian West has done a lot with Lua. One advantage of Lua is that when you change the Lua script, the very next call that gets sent to the IVR will see any changes that have been made. With the XML files you need to execute a 'reloadxml' command before the changes are seen. (I don't know about xml_curl but I would wager that changes on the back-end database that serve up xml_curl would show up with the very next xml_curl request. If someone could confirm/deny that statement with respect to IVRs that would be most welcome.) Whether you chose XML or Lua/Perl/js/etc. I would recommend that you study the demo IVR, especially the concept of phrase macros. Phrase macros let you piece together lots of sound files and add TTS, pauses, etc. so that you can build high-quality phrases. You can also use channel variables in your phrase macros which makes them a bit more dynamic. Once you're familiar with the basics then it's a matter of preference between scripting, XML, or xml_curl. Also, keep on the lookout for GUI-ish stuff because you never know when someone is going to create a front-end for this kind of stuff! ;) -MC
