Version 10 of Avaya messaging has an SNMP service that is supposed to send traps. I have not been able to get it to work yet but the config guide has a section that talks about it.
ucsnmpconfig.exe trap add --host=IPAddress [--port=xxx] --user=name [--authpass=pwd [--authtype=MD5|SHA] --
privpass=privpwd [--privtype=DES|AES128|AES192|AES256]] [--engine=engID]
