[Asterisk-Users] after hours logic

[Lance Arbuckle]

Hi.  I'm new to Asterisk and have been working on setting up a
development server but have gotten myself a bit confused.
I'd like to implement the following logic for calls coming from the
PSTN:

Check for caller-id
  yes    => keep going
  no     => play SIT and prompt for telephone number

Check time of day to see if it's day / night
  day    => ring some phones
            no answer ? => goto auto attendant
            let the caller select an extention
  night  => play special after-hours message
            goto auto attendant
            let the caller select an extention
            BUT, DO NOT RING THE PHONE
            INSTEAD GOTO THE EXTENSION'S UNAVAILABLE VOICEMAIL MESSAGE
  
I think I have a good start on this, but I can't figure out how to
modify the behavior of the extension phones in a manner that will easily
scale above a few extensions.  All I can think of is to have a seperate
[after-hours] context that has different GoTo's but that seems rather
cumbersome.  Any suggestions are welcome.
FLAME away if this is a stupid question :)
