Having exactly the same problem with 7905. In addition it doesn't seem you can 
disable (at least on my sip fw release) the redirect-to-vm-on-busy feature.

Whenever the phone has the VM number configured (and people like the 
"messages" button, sadly) it sends out "302" messages for the vm number when 
it's busy, regardless of any other config setting, which is _very_ bad for 
queues and acd.

I had to do a quick modification to chan_sip denying redirects to the (magic 
hardcoded) vm number.

Hope for a new release where you can either set the vm, vm-listen separately, 
or at least disable the redirect "feature".
