[Asterisk-Users] FW: NEWBIE: HOWTO make asterisk only accept calls when extension is picked up

[Ben Bosshardt]

I am running asterisk with a AVM euroisdn card and a few sip extensions. How
can I configure asterisk that the calls only get accepted when the extension
is picked up to avoid charges fort he called when I am out. I only want to
accept the call and send it to voicemail after 20s to avoid charges for any
called wanting to hang up before.

Thanks in advance
