This thread is intended to invite other 3CX users to share their ideas on how they have made improvements to the MOH. Some users suggest joining several MP3 tracks together and using a method to swap out the MOH file at random. Others have written scripts to accomplish this and some use scheduled tasks to change the file periodically. Are there any problems with file locking or problems that occur when you swap out a file that is currently being read by 3CX? What strategy has worked well for you? I also note that the quality of the MOH is often quite poor, even though the file sounds excellent when played via WMP. Do WAV files sound better than MP3 files and what is the best bitrate for MOH in the current version of 3CX? The floor is open.
