[Asterisk-Users] MPG123, Music On Hold and Variable Bit Rate

Chris,

My question was referring to the fact that Asterisk MoH cannot handle 
variable bit rate MP3 at this time. So I am under the impression that I 
have to modify my MP3 that I want to use for MoH to be at a constant 
bitrate for MoH to work properly.

Thanks,

Mike
