Re: [asterisk-users] mixmonitor extension
for the record. info about opus from Lorenzo Mniero (author of Opus patch for asterisk) with his permission --cite-- Opus is just a codec. In order to save an audio file using Opus, you need a container, which for Opus is OGG. Asterisk supports OGG, but I think it is implemented to only dump Vorbis audio, and so the existing module would need to be extended to support Opus as well. I haven't checked how complex this could be, to be honest, so I have no idea about how much effort would be needed for this. Right now we don't need it, so I really can't say if and when we'll start working on this.

Its a patent issue as Asterisk cannot distribute the software to write to mp3 under its own license. Its a similar issue with Opus as the codec is covered by a couple of patents in the USA. What most people do is use MixMonitor to record to .wav (alaw) and then in the 'h' extension call a program which runs a background task to convert the .wav file to whatever format they wish. Thats what we do but we actually use the Monitor application and we end up with both legs of the call and multiple sets of recordings if people pause and unpause. We then move these files off to a different server when they get mixed and converted to mp3 and then emailed out to our customers. We do it this way to reduce the load on the Asterisk boxes but also keep all the call recordings in a central location. -- --- Marek Cervenka === -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
