If calls hang-up mid message or during recording

This can happen when the hardware is misdetecting the end-of-call tone during playback or recording. If it happens during playback, turn off the "Enable end-of-tone detection during playback" option using the "End of Call Tone Detection Settings" from the Devices tab of Settings. If it only happens during recording, turn on the "Enable end-of-tone detection during playback" option but turn off the "enable software based end-of-call detection" option.
