If a Record module is created, it overrides the default record operation. Therefore it must at minimum emulate the default manual recording process of placing recordings into the mailbox of the user who triggered recording. For example, in the module call flow shown below, the Listen action is set to $UUI.
The $UUI Variable
The $UUI variable is supported from Voicemail Pro 1.3.15 onwards. Whenever recording is triggered, $UUI contains the user name of the user who that triggered the recording process.
