In-Depth Information
In this case, RMV is used to request that MWI should be turned off for the specified station number.
Note that one issue that can occur with SMDI on CallManager is that MWI is received but does not function correctly. In this case, it
is a good idea to check that the MwiSearchSpace field in the Cisco Messaging Interface (CMI) specifies the partition that corresponds
to the phone in question. (Partitions should be correctly configured—they are case sensitive—and separated by colons.)
SMDI Error Messages
SMDI error messages are sent using the following format:
<CR><LF>MWI stn-num!<0x20>error-code<CR><LF><^Y>
The error code can be one of the following:
■
INV:
Indicates that the station number is invalid
■
BLK:
Indicates a block condition
Call Handlers
Unity uses call handlers to process and forward calls based on input from users.
Call handlers consist of a specific set of instructions or actions that enable Unity to answer calls, play a greeting, prompt callers, take
messages, provide recorded information, and transfer calls.
Call handlers can be used for a number of simple or complex purposes, such as providing an auto-attendant, transferring calls, playing
messages, receiving messages, and providing audio text applications. Unity subscribers also have associated call handlers.
There are several default call handlers in Unity (which are undeletable), including the following:

Opening greeting
