What are the challenges of IP telephony?ĭespite the benefits associated with the use of IP telephony, its use can carry specific challenges: IP phones can be accessed beyond a physical office, from portable computers and mobile devices.įor more in-depth information on how VoIP technologies work, read our definition. Deploying new IP business telephone lines, which can be done through an online interface, is far simpler and easier than adding new wired phone lines. For example, faxes can be sent and received via email. IP telephone systems can integrate with existing infrastructure, enabling communications to work through business applications. Long distance and international calls are also less expensive with IP telephony. Using IP telephony is significantly more cost-effective than using wired phone services on a similar scale. Before IP telephony, businesses needed to deploy and maintain separate networks for internet and phone. IP telephony services can offer the following benefits to organizations of all sizes: What are the IP telephony business benefits? How audio travels across the internet with VoIP In 1995, Intel, Microsoft and Radvision began to standardize VoIP systems. The next year, InSoft released Communique for desktop video conferencing. IP telephony was introduced in 1991 with the creation of the first VoIP application, Speak Freely. Voice features within IP technology - such as voice calls and voicemail - are referred to as voice over IP (VoIP). These digital signals travel through IP networks, such as the internet, as data packets, using IP packet-switched connections. IP telephony works by converting voice calls, faxes and other information into digital signals. Using the internet, calls travel as packets of data on shared lines, avoiding the tolls of PSTN. Traditionally, these communications have been carried over the dedicated circuit-switched connections of the public switched telephone network ( PSTN). IP telephony (Internet Protocol telephony) is a general term for technologies, products and services that use the Internet Protocol's packet-switched connections to support voice calling, voicemail, video calling, video conferencing, faxing and instant messaging (IM).
