@darrenoneill I think I can do that on dial in. The conference auto mixes the channels, but if I were to set up the local recording to start on the channel and not mix them, it will create separate streams of each call. Capture those in signed linear, you should have a mono track of just their voice.
Lining them up may be a pain, but if you take a note of the creation date, you’d be able to quickly position the file in the DAW for mix down in post
