Re: [Pyst-users] is this a bug?

[Dax R. <ra...@gm...>]

I get the following on asterisk console when I 
call get_data
let it timeout
then call say_digits.

    COMMAND: get data demo-congrats 5000 255
    -- Playing 'demo-congrats' (language 'en')
    RESULT_LINE: 200 result= (timeout)
    RESULT_DICT: {'result': ('UNDEFINED', '')}
    COMMAND: say digits "UNDEFINED" ""
    RESULT_LINE: 520-Invalid command syntax.  Proper usage follows:
Traceback (most recent call last):
  File "/usr/local/share/asterisk/agi-bin/agi.py", line 516, in ?
    agi.say_digits(mydigit)
  File "/usr/local/share/asterisk/agi-bin/agi.py", line 231, in say_digits
    res = self.execute('say digits', digits, escape_digits)['result'][0]
  File "/usr/local/share/asterisk/agi-bin/agi.py", line 63, in execute
    return self.get_result()
  File "/usr/local/share/asterisk/agi-bin/agi.py", line 111, in get_result
    raise AGIException(code, usage)
__main__.AGIException: (520, '520-Invalid command syntax.  Proper usage follows:

In order to avoid 520 AGIException for this situation:

when agi asks for some input (get_data) then timeout without getting
any ( thus getting a result = {result:('UNDEFINED','')} ) and later
"playing/saying" the digits/number with digits = `"UNDEFINED"'

I have added something like

if digits = `"UNDEFINED"': return ''

in function say_digits
