Using Commands for Playing a WAV File
The IP Phones allow a WAV file to be played or stopped via XML Execute
commands. A WAV file is an audio file format standard for storing an audio bit
stream on a system in raw, uncompressed format or compressed format to reduce
the file size.
A WAV file can be streamed to the phone using the HTTP protocol.
The WAV feature supports the following:
• Streaming of the WAV file to allow it to be locally played
• Allows you to abort the audio streaming by pressing the Goodbye key on the
phone.
• Supports the HTTP file download protocol
• Supports the aLaw and uLaw codecs
• Calls “ Action URI INCOMING ” when the audio WAV starts, and
“ Action URI ONHOOK ” when the WAV file playing has completed. The
name of the WAV file is inserted into the Action URI.
• Plays the WAV file only if the phone is idle.
• Aborts streaming if another line is selected for dialing out, or if the current
line is accepting an incoming call.
• WAV audio file starts only when 4 seconds of the audio data (or the complete
file) has been accumulated.
• Follows the standard phone behavior of speaker/head set/hand set.
An Administrator can use two new XML Execute commands with the
AastraIPPhoneExecute object to allow the phones to play a WAV file:
• Wav.Play - This command initiates the streaming of a WAV file to the phone.
• Wav.Stop - This command aborts a WAV streaming.
