Message Waiting Indicator not working

[Jaiel Charette]

Hi all,

I have a setup with Cisco Unified Communication Manager v10.5 and Cisco Unity v10.5. I just finish setting up the voicemail but I'm not able to activate the Message Waiting indicator. I created 2, ON and OFF. But it doesn't show on my phone when I have a message waiting.

Thanks.

You only need one on and off per integration, is this SCCP???

If so, look into partitions and CSS to make sure the ports can reach the MWI DNs, and the MWI DNs can reach the DNs.

Yes it's SCCP but I dont have any partition or css configure. I'm new to CUCM and I'm not sure exactly how to proceed...

I would suggest you to start by reviewing the CUCM-CUC SCCP integration guide which covers all details, FYI a system with no CSS and partitions will only bring troubles down the line, it's the worst possible design in terms of dial plan.

If you're not familiar with CSS and partitions, I'd strongly encourage you to review the SRND dial plan chapter.

Ok thank you.
