4.6.1.4 Sampled Audio for Sound Effects <sampled_audio/>
The following sampled audio WAVE file (.wav) formats are supported:
• mono 8 kHz G.711 µ-Law
• G.711 A-Law
• L16/1600 (16-bit, 16 kHz sampling rate, mono)
The phone uses built-in wave files for some sound effects. The built-in wave files can
be replaced with files downloaded from the boot server or from the Internet, however,
these are stored in volatile memory so the files will need to remain accessible should
the phone need to be rebooted. Files will be truncated to a maximum size of 300 kilo-
bytes.
In the following table, x is the sampled audio file number.

If set to a path name, the phone will attempt to download
this file at boot time from the boot server;
If set to a URL, the phone will attempt to download this
file at boot time from the Internet.
Note: A TFTP URL is expected to be in the format:
tftp://<host>/[pathname]<filename>, for example: tftp://
somehost.example.com/sounds/example.wav
