[asterisk-users] Question about Read() application

[Danny Nicholas]

If you read the last line of the synopsis, it states that 
"Read should disconnect if the function fails or errors out."
 
I'm using Read() in an IVR context where I read an account number, then a password, then return information.  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.

What sort of "problem with Read()" are you expecting to encounter, and what do you mean by "keep going"?

Cheers,
Kingsley.
