The simple answer is no; the ling rings, the ringing is detected and
forwarded up the software stack.

The more complex answer is that first, the TDM410P doesn't actually know
anything about detecting ringing, ring patterns, or anything of the
like, it's essentially dumb hardware :-) The driver for the hardware
detects the incoming ring voltage and debounces it before reporting it
to the DAHDI core and then upstream to Asterisk; it is possible you
could set the debounce timer to require that the ring last at least
500ms (or maybe even a full second) before reporting it, which would
absorb these ring splashes.
