Maybe I can propose duration=0 means "automatic" and duration="very long" (or
-1) means "needs to be manually stopped or will last a very long time".

The DTMF GStreamer elements will queue them up and enforce a minimum duration
and pause that we've found to make most IVRs happy. The spec should probably
say something similar

Old DTMF was Rob and me, and it seems fine to me.
