Unit 7: Future of Networking Technologies

7. Fax to Email: Faxes can be sent directly to email addresses as attachments, without recipients Notes
even having a fax machine. There is no need to check for incoming faxes and privacy is no
longer compromised as a result of faxes sitting on a shared machine. Multiple faxes can be
received simultaneously and once received they can be saved and forwarded in soft-copy.

7.3 VOIP

Voice over Internet Protocol (VOIP) is a standard for software that digitizes and compresses
voice signals and transmits the bits via the internet link. Organizations can purchase the proper
software or use the services of companies that specialize in providing IP telephony. Companies
such as Vonage, Cablevision, Comcast, and many others offer inexpensive use of their VOIP
telephone-to-telephone voice communication.
Computer-to-computer calls can be conducted free of charge by using the service of a company
such as Skype or Jajah. Phone-to-phone service requires an additional modem, but it does not
require a new phone or phone number, and it does not require routing calls through a home
computer. Jajah also offers a free or low per-minute phone-to-phone service, if both the caller
and recipient register at the company’s web site. The caller uses a computer to dial, the caller’s
phone rings and when the caller picks up his phone the service dials the recipients number.
Thus, no VOIP modem is required.
VOIP can save companies and households money. According to the research firm In-Stat 20
percent of U.S. firms used VOIP in 2006, and two-thirds were expected to use VOIP by 2010.
Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies
for delivery of voice communications over IP networks such as the Internet or other packet-
switched networks. Other terms frequently encountered and synonymous with VoIP are IP
telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, and
broadband phone.
VoIP systems employ session control protocols to control the set-up and tear-down of calls as
well as audio codecs which encode speech allowing transmission over an IP network as digital
audio via an audio stream.

Notes Codec use is varied between different implementations of VoIP (and often a range
of codecs are used); some implementations rely on narrowband and compressed speech,
while others support high fidelity stereo codecs.
