</blockquote><br></div>If you only want to make video calls between SIP phones, then it should be OK.<br><br>If you also do video streaming to SIP phones, or if you need video telephony also to 3G UMTS video phones, then you need to patch Asterisk and I think then it is better to use a plain Asterisk version.

For video calls: no, just enable video in sip.conf (search for video in the sample config file)<br><br>For 3G UMTS video calls: yes. You need ISDN (or SS7) interface cards<br><br>For streaming (RTSP), recording and playback of video files: yes. You need the applications from<br>

How can we stream some static video contents through Asterisk.<br></blockquote><br></div>For example you can store the video as mp4 file. Then use mp4play() to playback the video to the caller. mp4play() is inlcuded in app_mp4.c (<a href="https://asteriskvideo.svn.sourceforge.net/svnroot/asteriskvideo/app_mp4/app_mp4.c" target="_blank">https://asteriskvideo.svn.sourceforge.net/svnroot/asteriskvideo/app_mp4/app_mp4.c</a>)

1. video is provided by Asterisk<br><br>SIP phone <--SIP+RTP--> Asterisk<br> ^ (using mp4play())<br> |<br> video.mp4<br><br><br>2. video is provided by a streaming server (e.g. darwin) and Asterisk (app_rtsp.c) bridges between the SIP call and the video stream.<br>
<br>SIP phone <--SIP+RTP--> Asterisk <---RTSP-------> Darwin<br> (using rtsp()) ^<br> |<br> video.mp4

<br>1. Install a "vanilla" (plain) Asterisk<br><br>2. Start with SIP-to-SIP video calls. By 2 webcams and use XLite to make video calls. (enable video in sip.conf)<br><br>3. Try also with the Echo() application. Then the caller should see itself.<br>
<br>4. Add app_mp4.c to Asterisk and reinstall Asterisk<br><br>5. Use mp4save() to record a video call from a SIP phone. Use mpeg4ip tools to analyze the recorded video (audio, video and hint tracks).<br><br>6. Use mp4play() to playback the recorded video to the SIP phone<br>
<br>7. use ffmpeg and mpeg4ip tools to create a video with hint tracks. Then playback this video to the caller using mp4play.<br><br>regards<br><font color="#888888">klaus</font>
