[Asterisk-Users] can X100P detect phone pick up like an answering machine

[Jim Flagg]

If Asterisk is configured as a simple answering machine replacement
with the X100P connected to PSTN line. No FXS ports in the 
Asterisk machine.  Standard phones are connect in parallel with
the X100P like you would a regular answering machine.

Can Asterisk detect that a phone has been picked up and cancel
the outgoing message and/or voice recording?  What about if the
phones are connected to the pass-through port of the X100P?

I know some PC software with voice modems can do this, just
wondering if X100P/Asterisk can do it?

Thanks
