Dial too fast?

I know there is a timeout for dialing too slow but is there a registration time for dialing too fast?

I have had a few complaints when people dial out, they here the “Cannot be completed as dialed” message. I checked their phones and their redial shows the full number but the log shows a missing number. IE: 123-456-7890 dialed, log shows 123-456-890

Thanks,
Shawn
