asterisk users - Nov 2005 - Stopping Asterisk from forwarding calls?

The first time I asked this to the list I didn't do a great job of it so
I'm posting again with more details.

Problem: when ringing multiple extensions, if one user has their phone
forwarded directly to voicemail, it stops the whole group from ringing
because the voicemail picks up immediately.

Also, after hours incoming calls are to ring all extensions so anyone
can pickup. But if one person in the office has their phone forwarded
the same problem occurs.

What we need is for asterisk, when ringing multiple extensions, to
completely ignore the forward requests and just ring the remaining
phones.

Reading the source code I see there are two parameters for channels,
allowredir_in & allowredir_out. These offer me some hope that Asterisk
has the ability but I couldn't figure out what these do or how to make
use of them (I'm not a C programmer so maybe its just a red herring?).

Those are entirely unrelated.

At this time there is no method available to make Asterisk ignore 
incoming '302 REDIRECT' from SIP phones. It may be possible to send 
those 'forward' requests to a context that has no valid extensions in 
it, but I don't think we even support that at this time.

A workaround (bvut slighty messy) would be to set up two lines on each
phone.
Standard calls (which can be forwarded) can go the first (main)
line/extension.
Group calls go to line 2.

Sounds to me like that you want to log the phones into a queue, then simply 
logout the phones that you don't want to receive calls.

If you were tricky, you could write a macro to log them in/out as they 
divert/undivert to/from voicemail. Eg. Dial an extension number to divert to VM 
(and log them out) then when they return, dial another number to do the reverse.

Then simply route the calls to the queue using a ringall method.
