Google? ;) You can create one though, using: - kind of OS "Sound Recorder" application, or - pjsip's recfile sample (you may need to set the configuration in the code). > At the moment I've got the app to the stage where it's streaming (or at > least it seems to be), but unfortunately it's streaming silence because it > can't read any of the wav files I give it, or they have the wrong number > of channels for the conference bridge :( Just FYI, the conference bridge from the latest SVN supports multichannel already (http://blog.pjsip.org/2008/03/31/doing-it-in-stereo/) Regards, nanang
