Music On Hold - 3300 MCD

[SaintyBob]

I am told that the Mitel 3300 MCD only supports 8 bit mono a-law wav files. Having experimented it seems that no matter how good the original audio is, the MOH sound quality sucks.
Anyone know of a better solution than the sucky Mitel one?

Thanks in advance

Try u-law not a-alaw.

You could use an external media player on the MOH interface on the back of the controller.
It still won't improve quality though.

Phone system network has a frequency range form around 300 HZ to 3600HZ, making your recordings reside in this range would help. Most pro audio recording don't adhere to what has been the standard for years. You might be best to trim the range before trying an import. Might not suck. How do recordings sound by vmail?

Thanks for the replies.
Actually, following some further testing the quality is acceptable apart from if the person on hold is on a mobile phone when it sounds really terrible even with good mobile signal. Maybe it is the mobile network doing something to it?

We find this with several systems that have embedded file based MOH... Avaya IP Office, Mitel 5000, Mitel 3300, ESI Comm Servers, Asterisks/Digium, and others, it is not a "phone system" issue per se, but the cellular network which is not designed to play continuous stream of sound like hold music, it is intended to carry voice which is actually very broken audio when you break it down into tiny bits.

Ace, you have hit the nail on the head here. This is one of the things that we struggle with the most to get customers to accept. Especially as more and more business seems to be done via cell phones.

Is music a requirement?  I tested a few on hold 'beep' styles and they were fine.  No continuous audio helps.
