Voice over IP (VoIP) has become a mainstream technology. Today, the question for businesses of any size is no longer whether to switch to VoIP, but when. The most important factor that has moved VoIP into the mainstream is improved quality of service (QoS). Businesses that have held back because of VoIP’s early reputation for poor voice quality no longer need to be concerned that important transactions (such as conversations with customers) will be impeded by poor quality. Today’s solutions with improved QoS deliver a professional experience and a positive impression of your company.
