I've got 5 sites each with CME running on a 2811. The default MOH (music-on-hold.au) has been working w/o any problems. We have had a professionally produced MOH file (in .wav format) that we would like to get into all the systems.
I've gone in an uploaded the file to the flash and adjusted the config to play the new MoH.wav file. At three of the sites the new MOH file plays fine. At two of the sites, the "music" is just static.
The new MOH file was tftp'd from the same source (across our MPLS cloud). When I do a sh flash command, the file sizes are the exact same both on the routers that work, and those that don't work.
Any ideas?

Hi,
Did you ever figure out what was happening?
Thanks,

I had a couple of things wrong.
1)I hadn't encoded the .wav file correctly to play.
2)I also had the E&M turned on to play MoH. If both E&M and telephony-service are configured to play different MoH files (or sources) the E&M wins.
