Sound Manager

• The Sound Manager automatically assigns a prompt number

Example:

• Choose Type IVR

• Give the IVR prompt a useful name

• Give the IVR prompt a password to prevent unauthorized users from erasing or re-recording the prompt

• Click Add when done and click Commit before attempting to record the prompt.

Recording an IVR prompt

There are various ways of recording any IVR prompt:

1. From a registered extension with a Class of Service that allows the Phrase Management feature code

   • Dial the Phrase Management feature code (default *55)

   • When prompted enter the prompt number followed by #

   • If the prompt is password protected enter the password at the password prompt and press #

   • Press 1 to record the prompt at the beep and press # to stop recording but do not hang up

   • Press 2 to review the prompt

   • After pressing 2 to review a prompt press 1 to re-record the prompt as many times as needed

   • Hang up to save the recording.

2. You can import a prompt file using the Tools>File Manager

   • But be aware that not all CODEC’s are supported by Asterisk.

Additional Information on CODEC’s

.raw files are signed linear slinfiles and slinis native to Asterisk | .slin is the preferred CODEC | .gsm .ulaw .alaware supported by most SIP hardware manufacture’s. | .g729 is not recommended due to licensing and CPU costs.

Playback of WAV/wav source file with Microsoft encoded output is not supported by Asterisk using Microsoft or Asterisk conversion tools.

The recommended methods are:

Using Switch Sound File Converter available from http://www.nch.com.au/components/switchsetup.exe

Set output format to .raw and set encoder options to16 bit format, sample rate 8 kHz, mono

Rename to .slin and then upload the file to the required /var/lib/asterisk/sounds/ directory or sub directory

or

Using Switch Sound File Converter:Output format .gsm, encoder options none and then upload the file to required /var/lib/asterisk/sounds/ directory
