Chapter excerpt:

What Is IP Telephony?
IP Telephony has been prevalent since the 1990s and seen as the future of communications, enabling various business verticals to transport multimedia over the IP network.

The major reason behind the prevalence of IP-based communications is the key benefits such as cost-savings, rich media service, mobility, portability, ease of integration with other applications, and rich features. With the ever-increasing awareness and adoption of IP Telephony, IP-based communication networks are now gaining popularity, and businesses continue to leverage VoIP platforms to handle all their communication traffic, whether it is voice calls, Instant Messaging, or voicemail. As IP Telephony technology matures, new voice services and applications will be offered and therefore resulting in yet broader acceptance and implementation of IP-based communication networks.

IP Telephony is slowly becoming an integral part of the modern day organization’s day-to-day operations. However, the benefits of IP Telephony do not come without cost.

The openness of modern day IP-based communications introduces new ethical, financial, and business continuity demands to protect networks and enterprises from internal and external threats and attacks.
