[timob]

Hallo,
ich in ziemlich nue mit Asterisk und frage mich ob jemand eine Lösung für mich sieht:

include = zentrale|08:00-18:00|mon-thu|*|* 
include = köhler|08:00-18:00|mon-thu|*|*
include = wegner|08:00-18:00|mon-thu|*|*
include = yarkin|08:00-18:00|mon-thu|*|*
include = brauer|08:00-18:00|mon-thu|*|*
include = SKA|08:00-18:00|mon-thu|*|*
include = yarkin_arch|08:00-18:00|mon-thu|*|*
include = discount|08:00-18:00|mon-thu|*|*
include = zentrale|08:00-12:00|fri|*|* 
include = köhler|08:00-12:00|fri|*|*
include = wegner|08:00-12:00|fri|*|*
include = yarkin|08:00-12:00|fri|*|* 
include = brauer|08:00-12:00|fri|*|*
include = SKA|08:00-12:00|fri|*|*
include = yarkin_arch|08:00-12:00|fri|*|*
include = discount|08:00-12:00|fri|*|*
include = intern
include = not_available|18:00-08:00|mon-fri|*|*
include = weekend|12:00-18:00|fri|*|* 
include = weekend|*|sa-su|*|*    
include = voicemailsystem

und

[weekend]

exten => 3052647e35,1,VoiceMail(99,u)
exten => 3052647e30,1,VoiceMail(98,u)
exten => 3052647e32,1,VoiceMail(97,u)
exten => 3052647e31,1,VoiceMail(96,u)
exten => 3052647e28,1,VoiceMail(19,u)
exten => 3052647e29,1,VoiceMail(29,u)
exten => 3052647e0,1,VoiceMail(39,u)
exten => 3052647e25,1,VoiceMail(49,u)

Wie kann es sein, dass Anrufe auf 3052647e35 am Freitag nachmittag TROTZDEM noch an "Zentrale" gehen ?
Vielen Dank schon jetzt für Eure Hilfe!
