[asterisk-users] bug in Asterisk 1.4.22?

[Abel Monzon]

Hello is my idea or this is a bug? The thing is that I have in my 
asterisk.conf this:
[directories]
astetcdir => /usr/local/etc/asterisk
astmoddir => /usr/local/lib/asterisk/modules
astvarlibdir => /usr/local/share/asterisk
astdatadir => /usr/local/share/asterisk
astagidir => /usr/local/share/asterisk/agi-bin
astspooldir => /var/spool/asterisk
astrundir => /var/run/asterisk
astlogdir => /var/log/asterisk

where the dir of agi-bin is in /usr/local/share/asterisk/agi-bin and inside 
agi-bin directory I have a file called a2billing.php and in my 
extesions.conf i have:
[a2billing]
exten => 11111,1,answer
exten => 11111,2,Wait,2
exten => 11111,3,DeadAgi,a2billing.php
exten => 11111,4,Wait,2
exten => 11111,5,Hangup

and then in my softphone I call to 11111 the asterisk log say this:
    -- Launched AGI Script /usr/local/share/asterisk/agi-bin/a2billing.php
  ==  a2billing.php: Failed to execute 
'/usr/local/share/asterisk/agi-bin/a2billing.php': No such file or directory
    -- Executing [11111 at default:4] Wait("SIP/abel-28c18000", "2") in new 
stack
  == Spawn extension (default, 11111, 4) exited non-zero on 
'SIP/abel-28c18000'

So, i change the file a2billing.php to another place and I change this new 
place in asterisk.conf:
[directories]
astetcdir => /usr/local/etc/asterisk
astmoddir => /usr/local/lib/asterisk/modules
astvarlibdir => /usr/local/share/asterisk
astdatadir => /usr/local/share/asterisk
astagidir => /new/place/asterisk/agi-bin
astspooldir => /var/spool/asterisk
astrundir => /var/run/asterisk
astlogdir => /var/log/asterisk

I reload the asterisk server and the asterisk log still say me the same 
place before:
-- Launched AGI Script /usr/local/share/asterisk/agi-bin/a2billing.php
  ==  a2billing.php: Failed to execute 
'/usr/local/share/asterisk/agi-bin/a2billing.php': No such file or directory
    -- Executing [11111 at default:4] Wait("SIP/abel-28c18000", "2") in new 
stack
  == Spawn extension (default, 11111, 4) exited non-zero on 
'SIP/abel-28c18000'


Why is that? Any suggest?

Thanks for all,
Abel
