asterisk users - May 2007 - how to define a key to decline incoming call

Hi all.
We have Snom phones which do have a defined key in order to drop incoming
call WITHOUT answering.

Pressing that key, a "SIP/2.0 486 Busy Here" message is sent back.

We have other phones (I.E. DECT Siemens C450IP, or ATCOM 320 or other)
which DO NOT have any key to do that (or the key does not work, as is with
Siemens C450 IP ): you have to answer and immediatly after hangup the call.

Acting on feature.conf we succed in defining keys for blind transfer or
attended transfer: the last thing we need is the ability to drop an
incoming  call without answering it. Is there any way to define a key (or
double-key, i.e. "*4") to send back a  "SIP/2.0 486 Busy
Here" message ?

thanks in advance,

Andrea

   Can't you do something like Hangup() or direct to voicemail from the 
features.conf directives?

   Never actually tried, so I could be blowing smoke here...

How are you proposing to seize the line to dial the feature code without
answering the call?

Please have a look at
http://www.voip-info.org/wiki/view/Asterisk+Cmd+Dial

Especially the M() parameter. There is an "example 2" that needs only
little changing to match your idea. You could, for example, wait 2 secs
in that macro before bridging the calls - and reject call if "1" is
pressed within 2 seconds, or similar.

Of course this prepends 2 seconds to any call bridging.

For the Siemens Gigasets, most of them (and I do not know the C450IP,
only the C450) show a soft button "Ignore" which meens "stop
ringing,
but do not tell the caller". Combined with a Dial() timeout and
following voicemail this works like "stop disturbing, eventually the
voicemail will take the call". No idea about the ATCOM though, so having
that Macro stuff might be the most universal method available.

Do these sets not have a "Do not disturb" button?

For sets that do, what is the behaviour when one presses the DND button
while the phone is ringing?
