[asterisk-users] indications.c: Can't generate that much data!

Simple. When using "r", asterisk needs to generate the ringing tones.
For some reason your indicactions.conf describe a tone which is longer
in duration than what can be generated by asterisk, so the error is
shown and no tone is generated. Probably the max buffer length is
somewhere preset in the code. If you do NOT use the "r" flag, asterisk
simply passes call progress indications from the source, without the
need to generate any. Hence no error, and you hear ringing.

Yes, it's a bug, but there no magic in the symptoms you observe.
