Hello,
After sending a video request while the callee's phone has the screen off, then if we attempt to send a video request while the callee has the screen on, the callee does not receive the video request (video request dialog is not shown on the callee's screen).
This seems to be due to code in linphonecore.c, which causes the caller's phone to permanently remain in 'CallUpdating' state after the video request is sent. Since the callee did not receive the dialog for video request (due to the screen being off), they were not able to respond to the CallUpdating status to end the callee's state. For this reason, further video requests are impossible during the call.
Please advise how this issue can be resolved.
