[Asterisk-Users] Stopping Asterisk from forwarding calls?

[John Lange]

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?).
