asterisk users - Feb 2005 - broken message waiting indicator on Polycom IP600?

Hello,

I faithfully followed the instructions from:

http://www.voip-info.org/wiki-Getting+MWI+on+Polycom+Phones+to+work+with+Asterisk

but still the message waiting indicator doesn't flash when a message is
waiting. There is a brief intermittent chirp but nothing more.

Using latest firmware 1.4.1

Thanks for your suggestions,

My only suggestion would be to make sure you've put the correct VM  
context in the phone's sip.conf section - i.e.
"mailbox="123@context".
It sounds like you must have done this, though, since you're getting  
the MWI chirp, just not the light.  Do you get the stutter on the  
dialtone?

It could also be one of the XML settings in the 1.4.1 firmware. I  
haven't gotten a chance to play with it much, but maybe you can turn  
off the MWI light, but keep the other MWI features on?  Did it work  
with other firmware versions?

Or, it could just be a bad LED.  Does the LED light up when the phone  
boots?
