I’d like to cobble together a videophone from an analog phone, connected to an Asterisk FXS channel, and a co-located video camera, connected to a video grabber card on the Asterisk server (so I have a Linux video device providing the video stream). When a call is made from the phone, I’d like to somehow add the video and produce a SIP
video call. I don’t want to use any sort of graphical SIP client;
ideally this should all be done headlessly in the Asterisk dialplan. Any suggestions on where to start?

  • Use command line video capable SIP software (linphone / linphonec) with source and modify it so an incoming call forwards to an outgoing destination with video added. You might want to talk to developers of linphone and ask them to make the change for you. Your analog phone calls to linphonec (probably using Asterisk) so that a call is routed to the SIP
    softphone. The softphone adds the video and send the combined audio/video SIP call back to Asterisk to be routed to the destination.
