Almost unlimited bandwidth, propagation of the Internet all over the world, multiplication of electronic devices with the processor power and capacity to connect, development of low-cost network technologies, open-source standards... all of this concurs to take network uses and services one step forwards, and invent new ones, too. In parallel to its work on the Pervasive Network, and independently from it, Ozone is also striving to contribute to the development of new, Pervasive Services: accessible from everywhere, in multiple forms, and adaptable to varied usage contexts. .

Teleph(oz)one

Teleph(oz)one is the very first Pervasive Service offered by Ozone.

Teleph(oz)one is an offer of Internet-based telephony. Like all other voice-over-IP packages, it offers unlimited - or deeply discounted - telephone calls. It gives access to a universal telephone service, thanks to which you can call anyone, anywhere, and anyone can call you by dialling an ordinary phone number.

However, Teleph(oz)one goes one step further in the field of VoIP by making full use of the open SIP protocol. With SIP, the flexibility, openness and universality we have become accustomed to with email is finally reaching the telephone. Phone number and service are now immaterial, personal, portable, adaptable. And now, with Teleph(oz)one:

Subscriber number and telephone line are no longer linked.

Unlike other broadband ISP’s telephony offers, in which the call number is attached to the subscriber's land line, Teleph(oz)one can be used from any Internet access, whatever the provider. The same call can arrive in separate locations, according to the user’s wishes: home, office, hotel room… the phone could even ring in all of these places at once.

The subscriber number is no longer dependent on a specific device or application

Teleph(oz)one subscribers can use an increasingly extensive range of devices and software applications to make and receive calls. The call number is not attached to any specific tool. Depending on circumstances, a user can choose to use a desktop telephone, software on his PC, a PDA, a portable Wi-Fi handset. A single device or piece of software can receive calls for several numbers. Likewise, multiple devices can simultaneously receive calls to a single number.

Teleph(oz)one is fully compatible with SIP standards. The subscriber can use any device or application that supports SIP, which is an open, non-proprietary standard. It is therefore already built in to most IP phones, Wi-Fi handsets, and commercial or free software applications*. According to his needs and preferences, the user can select any of a broad range of free or commercial solutions, offering a vast array of functions.

In time, telephony functionalities will cease to depend on dedicated equipment. Any device connected to the network will be “phone-capable”.

* with the exception of Skype, which uses a proprietary protocol not compatible with SIP

Extra services

The dematerialization of telephone services that SIP allows opens up major opportunities for the development of new telephone-based services. In addition to classic voicemail and call-forwarding capacities, SIP enables extensive functions for call filtering, customised automatic voice messages according to incoming call ID, alerts, redirections, intelligent logs and so on. The telephone will cease to be just a device to talk to someone remotely, but become a tool for comprehensive relationship management.

Mobility: the start of an alternative to mobile phone operators

Teleph(oz)one targets all users with broadband Internet access, whatever their ISP. Subscription and connection to Ozone's OzoneParis offer are not a prerequisite to benefit from Teleph(oz)one.

However, when he opts for Teleph(oz)one, a subscriber automatically gains access rights to the OzoneParis network for telephony-based applications*. When using a Wi-Fi mobile handset (these are offered by Teleph(oz)one), a Wi-Fi PDA, or a laptop PC, a user can receive and make calls on the go, as long as he is in an area with OzoneParis coverage… and, in time, anywhere.

* Access rights to OzoneParis are restricted to use of Teleph(oz)one and do not allow connection to the Internet or any other application.

The Pervasive Services philosophy

Pervasive Services do not follow the restrictive “Triple Play” approach currently favoured by most ISPs. Such an approach considers that all services must be dependent on a connection provided to the subscriber, who must therefore rely on a single ISP to provide them. This is a “real-estate” approach of network usages.

However, the generalization of IP as the transport medium for every type of data means that a telecom operator’s legitimacy as sole supplier of Services on their own network is illusory, or at best transitory. The network becomes merely a neutral transport layer.

New needs in terms of mobility, communications, fluidity, permanent access to one’s own data, free choice of content, as well as multiplication of electronic devices with the ability to provide a great many services simply by adding adapted software… all of this means Services must be reconsidered. Making the user central, rather than the network, means that Services must be redesigned so as to be accessible and usable wherever the subscriber may be, and not just where the ISP is.

To implement this vision and philosophy, Ozone’s undertaking is to rethink and develop applications for the Network.
