asterisk users - Dec 2004 - Problem with 302 "Moved Temporarily" Do not disturb

I have some Cisco 7905 phones with the SIP load 1.02.00(040406A).

When the phone is off-hook but no call has been placed, or when the Do
Not Disturb is activated, the phone returns a 302 "Moved Temporarily"
message back to asterisk as follows:

-----------

-- Executing Dial("SIP/5060-0811bb00", "SIP/9871234|20|Ttr")
in new stack
-- Called 9871234
-- Got SIP response 302 "Moved Temporarily" back from 24.xx.xxx.6
-- Now forwarding SIP/5060-0811bb00 to 'Local/8500@local' (thanks to
SIP/9871234-b2ca)

-----------

This forwarding doesn't work because the Voice mail system does not know
which extension was originally dialed so I either get a "please enter
the mail box number" or, if it is a local extension originating the
call, a "You have no new messages" message.

First, I need to know if it is the Cisco phone, or Asterisk that is
automatically doing the forwarding? It certainly is not something I
setup in the dialplan.

Second, are their any ways to trap a 302 message in the dialplan so it
does the right thing?

Third, (if not), are there any work arounds or suggestions for this?

Thanks,

Ok, it took me a while to figure out what this was doing but let me say
this is a thing of beauty and it works perfectly.

Here is the version I ultimately implemented with a couple of comments.

-----
; give voicemail at the traditional 8500
[voicemail]
exten => 8500,1,GoToIf($[X${RDNIS} != X]?${EXTEN},4) ; this allows call
forward to voice mail and therefore fixes the Cisco DND problem.
exten => 8500,2,VoicemailMain(s${CALLERIDNUM})  ; by passing callerid it
takes us directly to our own mailbox
exten => 8500,3,Hangup
exten => 8500,4,VoiceMail(u${RDNIS}) ; passing the original dialed number
gives us the correct mailbox.
exten => 8500,5,Hangup

Thanks greatly to Eric Wieling!
