## Discussion

If successful, you receive a callback from [`channelManager(_:channelUUID:didEndTransmittingFrom:)`](/documentation/PushToTalk/PTChannelManagerDelegate/channelManager(_:channelUUID:didEndTransmittingFrom:)) with `PTChannelTransmitRequestSource.programmaticRequest`; otherwise, you receive a failure reason through [`channelManager(_:failedToStopTransmittingInChannel:error:)`](/documentation/PushToTalk/PTChannelManagerDelegate/channelManager(_:failedToStopTransmittingInChannel:error:)).
