Prerequisites
To use this application you need a working Asterisk PBX with registered users in iax.conf, sip.conf or mgcp.conf(It depends on which protocol you would like to use) and made extensions.
To see how the application works we recommend you to use our IAX softphone Idefisk. You can download it from here. Please also read our tutorial to learn how to configure it to work with Asterisk PBX.

Asterisk PBX configurations
NOTE: This is only an example of what for you can use this application. Of course you can use it and for other things.
iax.conf Configurations
We need one registered user in the iax.conf file. This is because we are going to use the IAX2 protocol. If you want to use other protocol such as SIP or MGCP, you have to do the configurations below respectively in sip.conf or mgcp.conf.
So, we have registered the user user1
Type=friend means that this user can make and receive calls. Host=dynamic means that the IP is not static but dynamic through a DHCP server. Allow=all means that the line which this user will use, could support all audio codecs. Context=test - this shows that this user is working with the extensions in this context of the configuration file extensions.conf.

extensions.conf Configurations
Now lets take a look at the extensions.conf file.
On the picture above you can see our extensions.conf file.
We have the extension 100. When somebody dials this number, the call will be answer by the Answer application.
Next, we have the Dictate application with no arguments. When you do not use arguments in the brackets, the directory, where the recorded files will be stored, by default is /var/spool/asterisk/dictate/. However you can specify another directory as argument in the brackets.
When the execution reaches the Dictate application, the caller will hear a recorded voice, which will guide him through the Dictate menu.
The structure of the menu is the following:
When you press the pound key (#) and exit from the
Dictate application, the Hangup application will be executed.
In order to be sure that the Asterisk PBX will hang up the line after the conversation is over, it is a good idea to make an extension for hanging up the line.
NOTE: The Dictate application is making its files in .raw format.
So, if you want to convert them into another format (for example .wav), you can use the following command:
If your system does not have installed soxmix, you can install it by using the following UNIX command
