I am using SPA514g (7.5.2) phones with Asterisk (Elastix) and am having a problem keeping the "Message Waiting" setting set to "Yes". When this option is set to "yes" voice mail's light the MWI light as expected. The problem is when I make a change in the Asterisk server and apply the configuration. As soon as the new configuration is applied the setting on each phone changes to "no" and the light stops working. I then have to go into the admin page of each phone and set this call feature agian. Any assitance would be a great help.
