[Asterisk-Users] MWI not working on Polycom Phones

[Noah Miller]

Hi All -

I'm running version SIP version 1.3.4 on various IP300, IP500, and  
IP600 Polycom phones.  I'm having a tough time with MWI.  I thought I  
remembered somebody on the list saying that they had it working, but I  
can't find it in the archives now.  I have all the phones configured  
for MWI as specified in the WIKI:

ipdmid.cfg:
up.oneTouchVoiceMail="1"

phone1.cfg:
<msg msg.bypassInstantMessage="1">
   <mwi msg.mwi.1.subscribe="" msg.mwi.1.callBackMode="contact" msg.mwi. 
1.callBack="8500"/>
</msg>

I changed the callBack to the appropriate voicemail box (with context),  
but no dice.  No lights or indicators are coming on when there is a  
message, and pressing the "Messages" button on the phone just dials the  
extension rather than opening the VoicemailMain app.  Anybody have this  
working?  What have I fouled up?

Thanks,
Noah
