Description
YateUCN also implements a list of Network Sound Prompts to easy update the caller about the status of the call. A network prompt/sound is an audio message that informs the caller that the call cannot be completed or that the person he is trying to reach is not available at this time. In most instances, a network prompt sound is a prerecorded sound that informs the caller about the status of his call.
A caller might be entering a wrong number or is unable to make a call due to network congestion and will be notified by a network sound that there is a problem with his call. In other cases a network sound will be played if the outgoing calls are restricted and the caller has to contact Customer Care.
