Summary:                    false answer supervision
Description: 
Im using asterisk 1.4 with a2billing 1.3.2 for calling card operation.Every
thing works fine except answer supervision.

It is having 2 nos of FXO 24 port TDM cards one for incoming and other for
out going.When incoming call is received agi works perfecting and routes
call thru second card to destination,but the problem is even for voice
prompt (customer unavailable or switched off also) it is charging the cost
and deduction is occured in card balance allocated,this is false answer
supervision.

My current a2billing agi-conf1 :

[agi-conf1]

; the debug level
; 0=none, 1=low, 2=normal, 3=all
debug = 0

; Asterisk Version Information
; 1_1,1_2,1_4 By Default it will take 1_2 or higher
asterisk_version = 1_4

; Manage the answer on the call
answer_call = YES

; Play audio - this will disable all stream file but not the Get Data
; for wholesale ensure that the authentication works and than number_try =
1
play_audio = YES

; play the goodbye message when the user has finished.
say_goodbye = NO

; enable the menu to choose the language
; press 1 for English, pulsa 2 para el español, Pressez 3 pour
Français
play_menulanguage = NO


; force the use of a language, if you dont want to use it leave the option
empty
; Values : ES, EN, FR, etc... (according to the audio you have installed)
force_language =

; Introduction prompt : to specify an additional prompt to play at the
beginning of the application
intro_prompt =

Extension.conf :

[a2billing] - incoming
;CallingCard application
exten => s,1,DeadAGI(a2billing.php|1)
exten => s,2,Hangup

[outgoing]
exten => _X.,1,Dial(${RYRM-TRUNK}/${EXTEN})
exten => _X.,2,Hangup()

I Had made changes even in zapata.conf also changing below parameters.

answeronpolarityswitch=yes

callprogress= yes

progzone=yes

Still im having problem of fake billing and false answer
supervision.strucked from last few days on same issue,i had made changes
according to previous posts in forum,but still same.

Some one pls help me to resolve this issue.

Analog cards don't get answer supervision by default.  The only way right
now to get some sort of answer supervision is to either:

A.) Have polarity switch answer supervision enabled on your analog line,
like Tzafrir mentioned.

OR

B.) Use a card that supports a protocol that has answer supervision
inherent to it, like ISDN.

Analog lines are not a very good way to get reliable answer supervision,
as there is nothing across the board for each and every line that will
ensure any sort of answer supervision.

So, as Tzafrir mentioned, you best option is to see if your lines support
polarity switch answer supervision and try that option in zapata.conf.  I
don't know if that many lines support it though.
