Yes, the Omnicrons have a low voltage sense so they bridge across the line and capture CID if it's sent, and DTMF digits dialed on outbound calls. Your log shows the mechanics of the call.
I wouldn't try to share it with a video recorder, since voice recording on 4 ports is probably 1/2 again as intensive as the video at 240 frames per second.
We actually captured voice on an ME box running USB 1.1.
