This feature is useful for informing the recipient about the nature of the call before they answer it. This guide shows you how to perform a Call Whisper using SWML to inform the recipient the number of the caller. ## **Setting up the SWML Scripts** To perform a Call Whisper using SWML, you need to create two [SWML script resources](/platform/call-fabric/managing-your-signalwire-resources#swml-scripts). One will utilize the [connect](../../methods/connect/index.mdx) method to connect the caller to the recipient, while the other will use the [play](../../methods/play.mdx) method to play the Call Whisper message. ### SWML Play Example This will be the SWML script that is fetched when a call is successfully connected. In this example, we will play a message that says You got a call from , where is the phone number of the caller. This is done by using the say: command inside the [play](../../methods/play.mdx) method and using the %{call.from} variable to get the callers phone number. **Example** yaml andJSON version: 1.0.0 sections: main: - play: url: say:You got a call from %{call.from} ### SWML Connect Example {#connect-example} Inside the [connect](../../methods/connect/index.mdx) method, you can use the confirm parameter to specify the URL that will return the SWML script to play the Call Whisper message. The from parameter is used to specify the callers phone number, which will be used in the Call Whisper message. Here we are using the %{call.from} variable to get the callers phone number from the initial call. The to parameter is used to specify the recipients phone number. Please replace +1XXXXXXXXXX with the recipients phone number and the confirm parameter with the URL of the SWML script that plays the Call Whisper message. yaml andJSON version: 1.0.0 sections: main: - connect: confirm: https://your-space.signalwire.com/relay-bins/your-first-bin-url-goes-here from: %{call.from} to: +1XXXXXXXXXX ## **Conclusion** After setting up your [SMML](/swml) script resources, you can now use them to perform a Call Whisper. First assign the [connect example](#connect-example) script to a SignalWire phone number. Now, when a call is made to that phone number, the Call Whisper message will be played to the recipient before connecting them to the caller.
