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?
