Hi, I don't know of any H.323 endpoint that does sound recording. (That doesn't mean it doesn't exist because, conceptually, that is a simple thing.) I would suggest to use yet another machine, connect it with an audio cable and use simple sound recorder on that machine to record the file.

The scenrio will be transmitting the voice packets from one endpoint to the other in an emulated environment.I want the other machine to directly store the wav/au file.Is this possible.... I am asking this since i need both the audio files for objective testing. Are there any endpoints(VOIP) which support this.May i know the answer as soon as possible. -yamarthy
