Hi, I hope this is a relatively simple question but I seem to be chasing my tail around the Internet looking for a solution. I need a music on hold service that supports G711 and G729 at a minimum. I have converted the wav file to ulaw using sox and then to G729 using this tool: http://www.asteriskguru.com/tools/audio_conversion.php The theory is that having it pre-encoded removes any requirement to actually understand the codec you are streaming and reduces the resource requirements to a minimum. I'm hoping that this would be a very simple thing to do with PJSIP/ PJMEDIA since it already has support for dealing with RTP whereas most other frameworks I've found only do SIP, or where they do the audio too they need to understand or transcode it. I would also hope to end up with a simple set of files that can be copied onto a target system without a huge range of libraries, etc being required which also makes PJSIP look promising. If this isn't something that can be done with PJSIP a pointer in right direction would also be heartily appreciated.
