pbx_extension_helper: No application 'XXX' for extension (yyy, zzz, ppp)

11.5.1.3. pbx_extension_helper: No application 'XXX' for extension (yyy, zzz, ppp)

e.g.: WARNING[4421]: pbx.c:1652 pbx_extension_helper: No application 'Dail' for extension (mytest, 100, 1)

There are 2 possibilities for this warning:

1. Typo in the extensions.conf file

Have a look at your extensions.conf file for context mytest, extension 100, priority 1. Chances are big you made a type on that line.

It should look like a little like this:

exten => 100,1,Dial(.....)

a list with valid commands to put after this last comma can be found here:

2. This dialplan command does simply not exist in your version of asterisk

You might be using a dial plan command that comes with asterisk add-ons such as capi or misdn or h323, if you didnt install the add-on the application will not be available.

On the CLI you can ask for a list of all registered applications with the command:

show applications
