-----------------------------------------

Hi,

No, it is possible see 'B', 'C' and 'D' digits also. This issue occour many times during a call and virtually in all calls.
There is no specifc time to this issue, some times happens on start call, some times in the mittle and in other cases at the end.

Thanks,
Marlon
