So let me precede this by saying I think this may be an issue on HMP systems too from what I've observed. That being said...
After some interoperability testing, I've noticed DM3 cards experience a significant (over 100 milliseconds, probably less than 500) pause relative to JCT cards when they send back events to indicate the termination of a function such as playback or digit collection. Is there any way to reduce the time it takes to report these events back?
