Hi Thomas,  are you trying to say that, it takes input file as audio, but you havent mentioned the format type ? and also   GSM, PCMA, PCMU  , but this codecs needs to be converted again to play ? Still the picture is not clear to me. can you be more specific about the format and how does it transfer.  and does pjsip uses IPSEC Protocol which uses tunnel to protect the data, if yes, how ? wanted to know, a indiviual module, so that i can use it in other applications.

Hi.   GSM, PCMA, PCMU .. I doubt mp3, but you could just use some library for that and/or use mplayer/vlc/lame/ … to convert it on the fly   There is a sample program – I think it’s called streamutil.c which can take a file (or audio device) and stream it.   Regards   From:pjsip-bounces@lists.pjsip.org [mailto:pjsip-bounces@lists.pjsip.org] On Behalf Of Mukesh Srivastav Sent: Wednesday, July 16, 2008 5:53 To: pjsip@pjsip.org Subject: [pjsip] Audio Streaming..   Hi Benny,  i have  2 queries.   1) Does PJSIP support audio streaming, if Yes, then what  format does it support(Mp3,wav) ?   2) If PJSIP support audio streaming, can you tell me which module does that, can i extract that only core module ? is there any sample avaiable there ?     Let me know, all your comments.
