This document describes one reason why Cisco CallManager does not communicate with the Avaya Unified Messaging system through the Cisco VG224 Voice Gateway using the Simplified Message Desk Interface (SMDI) protocol. This document also provides a solution.

Problem
A problem exists when Cisco CallManager communicates with the Avaya Unified Messaging system through the serial port using an SMDI protocol such as Message Waiting Indicator (MWI) refresh / resynch.
In the corresponding trace, it is recognized that the Cisco Messaging Interface Service (CMI) is not receiving the SsInfoInd signal from Cisco CallManager. Therefore, subsequent signaling stops because CMI is not generating SMDI messages.
This output displays the corresponding error message on the Avaya Unified Messaging system:
failed to get integration data
