phone line appearance from their VoIP terminal adapter to an existing phone jack
(which is normally wired to the other phones already) after their landline analog
voice service is disconnected.
With the widespread adoption of the Internet and uptake of instant messaging, over
the top VoIP providers like Skype, Yahoo and Googletalk have assembled very large
subscriber bases. As before, these services were initially accessed directly from a PC.
However, customers are increasingly being served with dedicated Service Provider
branded appliances like the NETGEAR DECT Skype phone.
Video calling over IP allows a significant new service for consumers, a new revenue
stream for SPs and is still in its' embryonic phase. Only today's Service Providers can
popularize this innovative new method by tying today's phone numbering plan to
both Voice and Video calling. This may create a "sticky" new service and revenue
stream that is difficult for web site based competitors to displace.
To add voice and video calling to the mix, service providers embed servers and
media gateways (for interconnection with today's PSTN) to their networks that
control call setup, transmission and teardown for both the voice and video
services. When combined with consumers' Femtocells and mobile phones or
VoIP , landline analog voice becomes an obsolete service delivery method.
Service Providers on both the Cable and Telco sides will, over a few years of
transition, realize a huge service delivery cost reduction as their wired network
eventually collapses into four categories: broadband access platforms, SIP/
MGCP servers, core high capacity switching and transmission network elements.
Gone are the majority of baseband analog access platforms, media gateways,
huge buildings and most of today's maintenance, heating and cooling expenses.
This is similar to the transition that took place as Telcos transitioned from
electromechanical to electronic switching and from analog to digital carriers in the
1960s and 1970s as well as the transition from analog to digital that the Cable TV
companies started in the early 1990s.
