cisco 2651XM router
sip trunk registered and working.
cisco 7940G ip phone with firmware P00308000400
my sip trunk is working fine, I can make and receive pstn calls and I can dial *123 and pick up my voicemail. But my sip provider says I should see a text a message in the phone display when there are messages waiting for me and I don't see any notification on my 7940G phone. But if I use Xlite softphone on my PC it shows a little envelope icon so I know the sip service is working ok. How do I get my 7940G to notify me of waiting messages?
thanks for any help.
