[Asterisk-Users] Ignore incomingcall?

[Shawn Porter]

Is there a way to tell asterisk to ignore an incoming call?
I am using distinctinveringdetection and I am only interested in answering
calls
on the 2nd number.  Any call to the main line should just be ignored.

right now I have a context set for dring2 cadence 0,0,0
exten => s, 1, wait(30
exten => s, 2, Hangup

I thought that would sit until the max 4 rings (we have call-answer) then
disconnect itself, but
if someone picks up the phone asterisk keeps trying to respond to the call.

any thoughts?
