Dahua VTO2000A, SIP Firmware and Asterisk in Installation Help and Accessories Posted May 2, 2018 Just have everything running with SIP v3.3: - Videocall to GXV3240 with h264 - Call to Fritzbox phones with preview picture snapshoted when someone pushes the doorbell, also ffmpeg mjpeg solution with low framerate works. - Push notifications with Pushover and Telegram Only thing I really would like is disabling the stupid sounds like "calling now, please wait.." or "end of the call". Was that possible in the SIP fw from April 2017? Another thing is the preview video before answering the call on the GXV3240. Screen remains black until I push "video answer" button on screen. Does that someone have running? Maybe to specific..
