The default in 13 is "no" which still allows early media through. That
option has a complicated past.

Yes, because it's doing inband progress using a media stream.

Migrating asterisk 11 to 13: some callers get no ringback tone any more
Hello!
I migrated asterisk 11 to 13 as user of FreePBX 12.0.76.2.
As customer of German Telekom, I have three numbers and therefore three
trunks - each number is bound to one trunk.
After migration, some callers complained about missing ringback tone:
they didn't hear any ring tone and where surprised that they suddenly
got me anyway :-). The connection afterwards was as expected.
