 The configurability of the auto attendant is very flexible due to the use of a not limited number of menu states. When a call is answered by the auto attendant, the call is first in an initial menu state where a certain announcemnt is played and certain key depressions cause certain actions, specific to this menu state. A key depression (or a timeout) can cause a change to another menu, where a different audio file can be played and the key depression can cause different actions. There is no limitation how many menus you can use, and how the handled calls jump around between different menus.
-The audio files which are played back by the auto attendant (announcemnts or music) must be stored on an USB stick attached to the Internet gates USB port. They have to be stored in the directory /ivr. Also, they must be in .wav format, 8kHz sampling rate, mono, and PCMA or PCMU encoded. The easiest way to generate these files is to record them yourself by using the Record-function on the GUI-page for the auto attendant, where you choose a name for the recording, a telephone which shall be called to make the recording, and then you press the Record-button. The specified telephone will start to ring, you answer and - after getting a short beep tone - you say the announcement text into the telephone and hang up (or better press "Done" to avoid the hangup-klick). If you do not want to make the recording yourself this way, you can also copy the prepared audio file (with the specified format as above) on the USB stick e.g. on a PC. There is even the possibility - instead of using audio files stored on an attached USB stick - to use audio files (which must be in the same file format as mentioned above) from a http server in the network.

 As a specialized application you can program the auto attendant to act as a music on hold player. Just set it up to ignore all key depressions, to have a ring time equaling zero when being called, and to play back the desired music file in endless-mode.
