Hello, in the PJSUA manual (http://www.pjsip.org/pjsua.htm) there is a mistake: --play-file=WAVFILE tells me that the wav can only have one channel= mono but this is obviously not true as it plays stereo files as well (tested!). As this site is no wiki, I do not know how to correct it my own. Regards Matthias -------------- next part -------------- An HTML attachment was scrubbed...
