[asterisk-users] MoH with message on intervals

[Adam Moffett]

I'm talking to somebody who wants to have a recorded message play 
periodically for people on hold.

An example would be interrupting the hold music every two minutes to 
play a message with business hours and current specials.

Seems like you could fake it by breaking the music files into two minute 
chunks with alphabetical file names, and using sort=alpha. It seems like 
there might also be possible ways to do in the dialplan with 
'Set(CHANNEL(musicclass)=' or a combination of StartMusicOnHold() and 
StopMusicOnHold().

Can anybody point me in the right direction?
