We are receiving a lot of complaints about our 3CX phone system being broken for the fact the people are hearing prompts repeated when they expect to go through to an extension. I have tried my best to reproduce their complaints and, despite some of the wild theories, each time I have sat someone down with the system they can only get this to happen when they dial the extension really fast or really slow. The kicker is that our old phone system didn't get any of these complaints and I have yet to see a system that is less tolerant of fast or slow dialing. Has anybody had to deal with this in the past? Is there somehwere I can adjust the tolerance for how short of a DTMF tone is registered and how long the auto attendant waits before determining this is an incomplete sequence therefor causing it to repeat the prompt?
