[Freeswitch-dev] Lua session:playAndGetDigits regex

[Robert Clayton]

Anthony,

Yes and no. The original regex was a little more complex, it only got
simplified in the thread while trying to discover what was going
wrong.
Where we got "\\*|\\d{6}" to match either a "*" or "123456" the
original problem. It also allowed any entry if a single (or multiple)
asterisk were entered at any position in the entry string. Which would
be an incorrect action.

Correct: * and 123456 and does not match 1234
Incorrect: **, *123, 123 *, 12*24, 12**34, 1*2*3, etc.

Regardless, this was an interim step. What I need is two actions, the
first FS easily allows, the second the complicating factor.
1) Enter either a numeric string (either a defined length or undefined
length followed by a "#")
2) Enter an asterisk at anytime to allow reentry from the beginning
(returning without requiring a following terminator)

I tried to use the callback and filter the input myself but since (I
think) the callback only functions while the recording is playing that
could not be done unless I was sure either the user responded during
the recording or the recording was paused. Is there anyway for the the
callback to delay and not return at the end of the recording?
