Red light doesn't flash after received the call or vm

[xzjleo2005]

Hi

The red light doesn't flash on our 7941 and 7961 after a missing call come or leave a voice message. Does anyone could show me how to troubleshoot or should I configure anything on CUCM and Unity?

CUCM version: 4.1

IP phone firmware: SCCP41.8-3-3S

Thanks. Leo

Hi,

I've attached a troubleshooting guide for MWI problems. Make sure the on/off triggers are set in CCM and the ports are configured properly in Unity.

Does it work for all the other phone models?

It could be a restriction problem ! Be shure you have the MWI Ports in the right Partition/CSS

Thanks. I change the CSS configuration and now the red lamp will turn on when receiving message. But can the red lamp will be turn on as well when there is a miss call?

No, the MWI will be triggered by the uniy or unity connection ! patrick
