What is IP Telephony PBX PBA Doha Qatar?
IP Telephony PBX PBA Doha Qatar (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).
Traditionally, these communications have been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the internet, calls travel as packets of data on shared lines, avoiding the tolls of PSTN.
IP Telephony PBX PBA Doha Qatar works by converting voice calls, faxes and other information into digital signals. These digital signals travel through IP networks, such as the internet, as data packets, using IP packet-switched connections. Voice features within IP technology — such as voice calls and voicemail — are referred to as voice over IP (VoIP).
IP Telephony PBX PBA Doha Qatar was introduced in 1991 with the creation of the first VoIP application, Speak Freely. The next year, InSoft released Communique for desktop video conferencing. In 1995, Intel, Microsoft and Radvision began to standardize VoIP systems.
