How to use a wav file as Music on Hold
Jeromie
Create the announcement extension.
1) In CM, build an announcement. Announcement Name: cannot contain any spaces or special characters. In this example I used:
Annc Name:
Music1
Annc Type: integ-mus
Pick a VAL board where music will be stored. Rate will be left at 64.
If you do not want this file to be overwritten, select “Y” for Protected.
Capture of Music File from CD
1) Insert CD into drive on PC, open music with Windows Media Player.
2) Check the box next to the music file you want to RIP.
3) Now select
RIP – Format – WAV (Lossless)
4) Now Select
RIP – Rip “
Unknown Album…..” NOTE – your specific filename will be in this field.
5) After the file is RIP’d Media Player will probably give you this message;
Just click “OK” – it is nothing to worry about.
6) Windows Media Player will save the RIP’d file to the default directory (c:\Documents and Settings\jbstep\My Documents\My Music) where “jbstep2” is the actual user name of whoever owns the PC.
7) Wherever you place the file, make sure to rename it
exactly the same as the announcement name in the PBX. This example is “Music1”.
Converting the WAV file to VAL format specifications
1) Using any sound recording software available, you’ll need to down convert the WAV file into the proper format. I used a free program from NCH Software (
http://www.nch.com.au/index.html) called – Switch Sound File Converter. Whatever program you use, ensure that it does not imprint the converted sound files with a brand name or audio-logo.My procedure will outline how to make the conversion using the NCH software. If you use something else, the procedure will be similar in concept, but you’ll have to figure it out.
2) Open your source file (the music you want to convert) by clicking
FILE – OPEN– then
Music1.
3) Click
EDIT – CONVERT SAMPLE RATE –
8000
4) Click
EDIT – CONVERT CHANNELS –
MONO
5) Click
FILE – SAVE AS – (place the file where you can find it) – then
SAVE – Wave Encoder Options – Format =
CCITT µ-LAW Attributes =
8,000khz, 8bit, MONO (should be preset already)
6) Click
OK
The music file should now be down converted into the proper format. Remember exactly where this file is now. It would be a good idea to play it all the way through once (to be sure nothing unusual or offensive has been recorded).
VAL Manager Setup and Insertion of File
1) Open VAL Manager – Click System – Register Voice System
2) Populate the Voice System Name and IP address of your CM. Leave port at 5022 (if you are connecting via SSH, which you should be).
3) Input the Login Name: and Password: to access the CM. You may want to setup a login just for VAL Manager in CM, just to keep track of all login activity.
4) Click OK to commit changes.
Backup and Capture VAL Board Information from CM
Back up:
First thing to do is execute a full system backup of all VAL and vVAL board files to your local PC (or wherever drive you choose)
1) Right Click on
Voice Systems (located in left hand pane).
2) Select
Back Up All
VAL Manager will begin a full backup of all announcements stored on VAL and vVAL boards. These files are saved at: C:\Documents and Settings\OWNER\Application Data\Avaya\Voice Announcement Manager\user\VOICE SYSTEM. NOTE – the red highlighted folders will be unique to the PC owner and the VOICE SYSTEM will be the name of your system in VAL manager.
Capture of VAL Information:
1) Right Click on your systems name (example here is VA_ORM)
2) Select
Get VAL Board Information
3) A
Get VAL Board Information status window will display.
After complete you’ll see an acknowledgement window which will affirm a successful download.
Transfer of WAV file into VAL board
1) Click to open your system (example VA_ORM)
2) Open
Audio Sources
3) Open
Default Folder
4) Right Click the VAL or vVAL board you want the WAV file to reside on.
5) Select
Copy / Delete Audio Files
6)
Retrieving Announcement Properties progress window will appear. Right now the VAL Manager is collecting all the specific announcement / music files already resident on your chosen VAL or vVAL board.
7) Once the
Copy/Delete Announcement Files window appears use the “Change Folder” button to navigate to the converted WAV file.
8) Your source file will be in the left hand pane (Files on Local PC).
9) Select your source file, then click on the single > button. This will automatically begin the transfer of your WAV file into the VAL or vVAL board. Remember – the source file name has to be exactly the same as the announcement name you created in the CM. Once the file transfer begins, VAL Manager will install the WAV file on top of the already existing announcement. If the two names are not the same, you’ll have an unassociated file to deal with in the CM. That is not a show stopper, a little poking around will get the file properly associated, but it is easier to just make everything line up from the beginning.
10)
“Copying Audio Files to….” will appear. This shows you the status of your transfer.
11) Then the VAL Manager will begin Copying the file to the VAL or vVAL board (this is a good indication that everything is working properly)
12) Once completed, the Copy files Task window will be displayed. Any ERRORS means a failure. Refer to my Troubleshooting section at the end of this procedure.
Checking your File
To make sure your file has indeed been transferred, double click the VAL board. This will download all the file information for that board. Look for the
Music1.wav file. Scroll to the right, look in the
Length column. There will be a value here displayed in seconds. This example shows 374 seconds (a little over 6 minutes). You file has arrived.
Configuring CM for Music On Hold via VAL
1) Execute
change moh-analog-group 1
2) Populate field 1: with VAL board address.
3) Enter (f3)
Place a call to another phone on the same system, place on hold, and listen for music.
Troubleshooting
The only issues I encountered were all caused by the same thing, not having the WAV file in the proper format. The answer came from the VAL Manager HELP file. That document told me everything I needed. The WAV file text states the following;
Under
Using Voice Announcement Manager –
Creating and Converting Audio Files –
VAL Audio Format Requirements –
- “CCITT A-Law or CCITT µ-Law companding format (do not use PCM)
- 8KHz sample rate
- 8-bit resolution (bits per sample)
- Mono (channels = 1)
Note:
Mu-Law companding is used in the United States, while A-Law is used internationally. Ensure that you use the same companding format as the administered format on page 1 of the system-parameters country-options form.
If any of these parameters are not correct, the WAV file will not transfer. You will see it trying to transfer, but the attempt will result in ERRORS.
After I fully converted the WAV file correctly, everything worked as designed.
Lastly – MOH sourced from a VAL board works great. The file will loop over and over automatically. The music begins from the beginning as soon as the caller is placed on hold. TN 2501AP VAL boards can store up to 60 minutes of audio. A vVAL board can store up to 15 minutes of audio. It always works and the volume level is perfect (I do not know of any way to change the audio level once the file is installed on the VAL or vVAL board. If a lower volume is required, adjustments can be made in the Sound Recorded software, then re-save and transfer new file into system).
