I have an interesting issue with my sip provider. I received the MWI status in the debug messages, however my phones do not light up for MWI. I have a stripped down configuration attached. I have heard its related to codecs, but I have my codecs in place. So perhaps someone can look at my config and potentially identify an issue that could cause the MWI from not lighting up on my sip phones. I am running CME only not CUCME.

Can you please explain what you mean by MWI in relation with your service provider? As @Nithin Eluvathingal wrote there are AFAIK no way that this could be controlled by the service provider for your phones.
If we’re missing the point here and you do have CUE for voice mail in your CME setup please provide us the details on that configuration.
