Over the recent years enormous changes in the telecommunication services, techniques, regulations and markets have taken place. However, even with many new exciting services the telephony service is still popular. This paper provides empirical traffic data and observations of telephony traffic patterns in mobile and IP telephony. They are presented and compared with old telephony patterns from ...

Telephony over IP (ToIP) is a cost-saving communication technology based on voice (VoIP) that enables enterprises to reduce fees. However, ToIP faces many security threats due its IP-based nature. This work aims improve using cryptography and blockchain technology. The authors propose secure approach user registration, authentication, session establishment, data storage. proposed solution lever...

The global telephony infrastructure is rapidly evolving from circuit-switching to IP-based packet-switching. Voice over IP (VoIP) is becoming common and is the intended base technology for corporate giants such as AT&T and Qwest. The marketing research firm, IDC, states “IP telephony is poised to become the fastest-growing, network services market of the decade” [1]. Reference [2] reviews the m...

Voice over Internet Protocol (VoIP) is a rapidly emerging technology. Currently, the Internet is being wired to support voice and fax traffic. The widespread interest in VoIP is not necessarily the ability of IP to carry voice traffic but the ability to carry voice and fax traffic over data networks. The implications of this are far-reaching. That is, the Internet, for the most part, will event...

The Internet is under rapid growth and continuous evolution in order to accommodate an increasingly large number of applications with diverse service requirements. In particular, Internet telephony, or voice over IP is one of the most promising services currently being deployed. Besides the potentially significant cost reduction, Internet telephony can offer many new features and easier integra...

While Internet Telephony (IP Telephony) encompasses many different architectures and services, the key idea is the transport of real-time voice traffic over the Internet. IP Telephony architecture [2] allows the entire end-to-end path or a portion thereof to be routed over the Internet. The endpoints are regular personal computers (PCs) that are equipped with IP Telephony software which allows ...
