Hi Peter,
If I understand you correctly, you need to find a file that will play Music On Hold (MOH).
Mitel doesn't offer the "Music On Hold" source files. Each customer is expected to either come up with their own source or work with their vendor to come up with it.
I'm not sure what SIAI is but I would assume that it's the same as
ASCAP here in the states.
This is where you'd pay royalties to here in the US (and Canada I believe). It's a yearly fee and applies to things like CD's and even playing radio stations over MOH.
Not every piece of music requires yearly royalties. There are other sources for royalty free music or nearly free. Not easy to find but they're available. Then you have to get them in the right format for the Mitel. 8 bit mono A-law or U-law.
I'm a bit ahead of my self talking about this but I'm actually working on a website that is specifically designed to provide Royalty Free Music on Hold. The intent is to sell for a one time fee quality music that does not require a yearly ASCAP licensing fee. ( I know, you can call the one time fee a royalty fee if you want but it's a one time fee.) My son is going to school at Michigan Tech University for Audio Production and happens to be an accomplished musician. He has put together a couple of pieces that we're going to start with and then allow other students to add their music so they can earn a bit of money for their tuition. The website I'm putting together is
www.University-music-on-hold.com It's not ready to sell the music yet but should be ready soon. Everything will be available for download formatted for the Mitel, as an MP3 or on CD.
I do have a couple of pieces available I can sell you for about $10 US. I'd just give it to you if I could but it's my son's an that how he's earning income for his collage tuition. Let me know and I may be able to provide you with samples.
