[asterisk-users] Answering machine answers after pickup a phone.

[John Novack]

Completely normal operation.
You need to read and understand more basic telephony and analog lines to understand why that won't work.

Asterisk needs to be in control, and once someone answers a phone not under Asterisk control, or the call is abandoned there is little you can do.
Sounds like a task for a simple answering machine from Wal-Mart
All you other phones should be connected to FXS ports, or you need to be smarter in your dialplan.
Once you answer, Asterisk is behaving normally
