Mute Emergency Call

Mutes the local audio stream of an active emergency call. When muted, the emergency operator will not be able to hear you, but you will still be able to hear them.

Signature

// Callback version
fun muteEmergencyCall(
  callId: EmergencyCallId,
  callback: (Exception?) -> Unit
)

// Suspend version
suspend fun muteEmergencyCall(
  callId: EmergencyCallId
)

Parameters

Parameter	Type	Required	Description
callId	string	Yes	Unique identifier of the emergency call to mute

Return Type

Returns void (or Promise<void> for JavaScript/TypeScript). The method completes successfully when the call is muted, or throws an error if the operation fails.

Usage Example

// Callback

client.muteEmergencyCall("callId") { err ->
    err?.let {
        // Handle Error in muting emergency call
        println("Error in muting emergency call: $err")
    } ?: run {
        println("Emergency call muted successfully")
    }
}

// Coroutine
try {
    client.muteEmergencyCall("callId")
    println("Emergency call muted successfully")
} catch (e: Exception) {
    // Handle Error in muting emergency call
}

Notes

• Muting affects only the local microphone - you will still hear the emergency operator
• Use unmuteEmergencyCall to unmute the call
• The call must be active and have an established media connection
• This is a local media operation and does not require server communication
