Now let’s expand upon the test dialplan we started in the previous section, allowing us to dial back into the softphone after we have configured it and to use a dialplan application called Echo() that will allow us to test bidirectional audio. We’ll learn more about dialplans in Chapter 5, so for now, just add the italicized bits to your existing extensions.conf file. We’ll be making use of this dialplan throughout the chapter, and expanding on it in certain sections. Once you’ve entered the text into extensions.conf, reload the dialplan by running dialplan reload from the Asterisk console:
