Asterisk supports EURO ED 137-1B

Does Asterisk support RTP Packet as mentiond in EURO ED-137-1B???
Please Advise EUROCAE: tInteroperability Standards for VoIP ATM Components (Aeronautical industry consortium).

I think the answer is not deliberately, except to the extent that the standard only codifies best practice. I doubt that the PTT signalling is implemented, unless it was done for amateur radio use to the same standards.

Really, you will need to go through the specification and the code. Unless ED-137 appears in the source code comments, it is very unlikely that any will know for certain without doing that cross match of the code and he specification.
