I have a SX20 and EDGE 95. When a call is placed from SX20 to EDGE and input is switched (so far end doesn't see any incoming video), EDGE decides to show a frozen image of the camera instead of blanking out the image. If the call is placed from EDGE to SX20 or SX20 to any C-series Codec, it works as expected and shows a black screen.
The firware version on SX20 is 6.2. Is it something inherent to C-series codec when placing call to legacy products or something in the firmware that can be correct?
Can anyone please advise?
