[All 300-810 Questions]

A collaboration engineer is troubleshooting MWl issues with Cisco Unity Connection and Cisco UCM. Users report that MWl lights do not work when a new message is received. After doing a packet capture, the engineer notices that Unity Connection sends a SIP Notify to Cisco UCM for MWI.Cisco UCM responds with a SIP 503 Service Unavailable message. Which action resolves the issue?

Show Suggested Answer Hide Answer
Suggested Answer: A

This option is the correct action to resolve the issue of MWI not working when a new message is received. The SIP server list on the Cisco Unity Connection port group defines the destination addresses for SIP messages, such as MWI notifications, that Unity Connection sends to Cisco UCM. If the SIP server list does not match the device pool settings on the SIP trunk, Cisco UCM may not be able to route the MWI notifications to the correct devices, and may respond with a SIP 503 Service Unavailable message.

Option B also makes sense. Assigning the proper voicemail profile to the directory numbers on Cisco UCM could ensure the integration is set up correctly.

I'm leaning towards option A or B. Seems like the most straightforward ways to address the SIP communication issue between the systems.

Yeah, I think the key here is to figure out why Cisco UCM is responding with a 503 Service Unavailable message. That's probably the root cause we need to address.

Agreed. I'd start with option A, since it's specifically addressing the SIP server list settings. Gotta make sure those are aligned on both sides.
