1. ChangeMonitor - this application allows you to change the filename of the audio file set in the Monitor application.
NOTE: This application is valid for Asterisk version 1.0.9 and above.
ChangeMonitor(filename_base) ; the argument is the desired new filename
Purpose and usage
The purpose of this application is to allow you to change the names of the audio files recorded by the Monitor application. ChangeMonitor works only while the channel is monitoring. It does not work if the channel is hung up or the StopMonitor application is executed. So, it is obvious that this application is always used with the Monitor one.
To see how the application works we recommend 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.
We need two registered user in 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 anatoliy and ivan
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.
So, in our example when somebody dials 12345, the call will be answered by the Answer application. The next executed extension will be the one which contains the Monitor application. As you can see the desired name for the audio file is proba.
Now, the next extension will execute the application ChangeMonitor. It will rename the audio file from proba to the one, specified in the brackets of the application. As argument in the brackets we have set nenam. So our audio file will be named nenam. The file will be saved in the directory /var/spool/asterisk/monitor/. You can change it in the asterisk.conf file.
Then we have the extension with the Dial application. Thanks to it, the call will be connected to the user ivan through the IAX2 channel.
In order to be sure, that the Asterisk PBX will hang up the line after the conversation is over, it is always a good idea to make an extension for hanging up.
