No, as far as i know there is still no "final fix" for the problem.
However you can choose to decode as T.38 as follows:
The problem is that some RTP decoding is applied before the user Decode
As... choice is applied.
This is most likely due to H.225 or similar signalling which sets up the RTP
conversation.
So, to prevent automatic RTP decoding you might consider disabling the H.225
or similar protocol.
This will result in the corresponding RTP/T.38 packets not being decoded as
RTP (they will remain UDP).
Then you can enforce these conversations to be decoded as T.38
