>          Components: Resources/res_fax
>    Affects Versions: 13.29.1, 16.6.1, 17.0.1

> A previous patch:
> Gerrit Change-Id: I73bb24799bfe1a48adae9c034a2edbae54cc2a39
> Made it so a T.38 Gateway tries to negotiate with both sides by sending T.38 negotiation request to both endpoints supported T.38 versus the previous behavior of forwarding negotiation to the "other" channel once a preamble was detected.
> This had the unfortunate side effect of breaking some setups. Specifically ones that set the max datagram option on an endpoint configuration (configured max datagram was not propagated since Asterisk now initiates negotiations).
> Make it so this patched functionality is itself wrapped in an option, so the use case happens for it only in those setups requiring it.
