SfB Server 2015 - max size of the hunt group configure music on hold audio file RRS feed

  • Question

  • 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! :)

    Have you looked at this link?

    All wave files must meet the following requirements:

    • 8-bit or 16-bit file

    • Linear pulse code modulation (LPCM), A-Law, or mu-Law format

    • Mono or stereo

    • 4MB or less

    For the best performance of wave files, a 16 kHz, mono, 16-bit Wave file is recommended.
