FreeSWITCH excels at letting multiple parties connect to a single conference "room" where they can all hear and speak to one another. The default configuration has some examples of conferences that we can use as a starting point. Keep in mind that in FreeSWITCH, there is no need explicitly to "create" a conference room—the
conference dialplan application does all the work for us.
In addition to a text editor, you will need at least two phones for testing, and preferably another person or two so that you can verify that your conference rooms are working. Also, make sure that you have the default FreeSWITCH configuration installed and the sound and music files added.
Follow these steps:
Dial 3000 and listen. You will be put into a standard conference room, and if you are the only person there, then after the announcement, you will hear hold music.
Dial 3000 from another phone, and both persons are in the same conference.
