[Freeswitch-users] Help with early end to ringback when calling PSTN?

Hello all, great project!
In the simple case of dialing out through a small 4 port fxo
(grandstream-4104) there is an unwelcome ringback silence gap of almost
exactly 10 seconds while the fxo goes offhook and issues its dtmf, then
the audio resumes with whatever audio the PSTN sends in response to the
dialled number.
I've tried to continue the ringback music using ignore_early_media=true
with no success. Tried transfer_ringback, instant_ringback, no joy.
In the following short fs_cli trace no matter what I try the music stops
at the point below noted as 12:19:44... and there is silence until
12:19:54... when the PSTN provides audio. What can I do to keep the
ringback music going until the log point noted at ...:54xxxx below?
