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.
It seems not to be phone issue. If your Asterisk is ordering the phone to turn the Message Waiting to NO, then the phone have no option but follow the order.
Your Asterisk needs to either:
But how to do with your Asterisk's distribution I don't know. This is forum related to SPA IP Phones, not Elastix. You should ask in an Elastix-related forum ...
Sorry, mail fault, I had a bad configuration on asterisk, phones work like a charm, but I'm still finding the web interface bug on SPA514, but that's not a big deal.
