# Introduction
`IMS` is a command introduced with [MSNP3](../versions/msnp3.md).

It is a Notification Server command, without either a request or response payload.

It enables or disables switchboard access without modifying the user's current status.

# Client/Request
`IMS TrID [ ON | OFF ]`

# Server/Response
`IMS TrID 0 [ ON | OFF ]`

Where `0` has an unknown purpose.
Rumored to be a timeout of some kind. [Please confirm this.]

# Examples

## Turning Switchboard access on
```
C: IMS 1 ON
S: IMS 1 0 ON
```

## Turning Switchboard access off
```
C: IMS 2 OFF
S: IMS 2 0 OFF
```

## Invalid argument
*NOTE: There is no defined behaviour for this command specifically.*
```
C: IMS 3 TOMORROW
```

Server disconnects client.

# Known changes
* Removed in MSNP24... probably? Who really knows... Only WebTV supported it, which only has [MSNP3](../versions/msnp3.md) and [MSNP8](../versions/msnp8.md).
