Typically at least for the ones I usually build out, the configure music on hold audio file is a very small ring tone wav file so that callers hear a nice 'phone ring' while their call gets transferred to the response group.
I'm building one out that for this file its a long, pre-recorded human voice greeting. I plugged in a WAV file that was about 3.3 MB in size, that resulted in the error that when the number associated with this hunt group was called, it beeped three
times and the call dropped. So I encoded the WAV to a lesser quality, got it to be about 1.2 MB, plugged that in, test calls worked fine. The audio is less quality of course, but still clear enough.
My question for the community is I can't seem to find any documentation about the maximum size of this file or the optimal type / encoding of the sound file. Based on my informal tests, it seems that WAV files under the 1.4 MB size seem to work best.
If there's anyone with past experience "pushing the limits" on this specific audio file, I'd love to hear from you! :)
