[asterisk-users] Question about Read() application

[Danny Nicholas]

The user reported to me that "I punched 1 and it hung up" - in my testing, I found that slow DTMF entry (1 digit every 2 seconds or so) or fast entry (more than 10 digits per second) was most likely to cause the problem.

Do you know if the failure was caused my user action (or lack of, ie they didn't send digits), or a technical problem?

Cheers,
Kingsley.

This usually works well to the tune of 44K transactions a month, but I will have around 1 percent of my calls ask for the account number and hang up the call because Read() failed and didn't say anything.  Perfection doesn't seem necessary until somebody complains because you don't have it.
