music on hold without mpg123



I have found in the past that using the "resample -ql" option gives better results.

Hi Matt,
thank you for your inputs. I updated the page at http://www.oinko.net/astrecipes/index.php?n=152 so that it merges in the new pointers you sent me.


I also think that converting to the native codec format will be the best choice - you can usually trade in some disk space for performance. In any case, even having everything as WAV will require only a relatively cheap encoding, and not the full mp3 -> slin -> {your codec} encoding plus the external process that mpg123 used to require.

I wonder: is there any way to use Asterisk as a transcoding tool, i.e. using its internal transcoding capabilities to transcode a given file to all its supported codecs? (I'm thinking of g729 and ilbc, things that are not supported by Sox but that might be useful in a real-life scenario....)

Thank you
l.

Lenz,

This method is referred to as file-based or native MOH, and I have some additional information regarding it. First, a short post on why we moved from the rawplayer method to native MOH on our production box, with a quote from Kevin Fleming regarding the impact the change would have on scalability.

Second, I *believe* (please correct me if I'm wrong) that in order to get the full benefits of native MOH, the music files should be converted to the codec that the calls will be in. This allows Asterisk to play MOH without performing any transcoding, which lowers the resource utilization on the box. Here is a guide for converting WAV files to the desired codec, which addresses the four characteristics that describe audio data.

Please feel free to add any of this information to your site and don't hesitate to contact me if you spot any mistakes.

Thank you,
