Online Cloud Telephony in The Spotlight

In the family of unified communication solutions, we are asking for WiFi VoIP phone service!

It comes in the context of the end of the traditional telephone network and analog telephone numbers within 5 years.

We are deciphering the telecom language for you and help you discover the future of corporate telephony.

Change is now!

The end of an era

French telecommunications company, Orange (formerly France Telecom) is one of the largest mobile service providers in the world. They focus on giving customers a wide array of services such as mobile, landline, internet, and IPTV (Internet Protocol Television), which is the streaming of television over WiFi.

Although fixed landlines are still widely used, Orange announced on November 2018 that all traditional fixed telephone subscriptions will no longer be offered. Orange plans on migrating to a completely digital network. 

They will remain operational until 2023 when the operator will completely shut down the traditional PSTN (Public Switched Telephone Network) and PBX system (Private Automatic Branch eXchange).

As it is already the case for many households, telephony will then pass through a box or an IP box. 

In the United States, there are currently about 115 million fixed lines, regardless of their connection.

In 5 years' time, some of these lines, still at low speed, will, therefore, have to be switched to ADSL.

What is the alternative to the private switchboard called PABX or PBX?

The alternative is telephony via a WiFi network, allowing VoIP phone, Voice over IP.

Also called IP telephony or hosted telephony, it is a solution hosted on a server by a specialized operator, which passes through a router and over the Internet. 

Several systems exist:

  • IPBX
  • Centrex IP
  • Virtual PBX

VoIP, IPBX, Centrex IP, Virtual PBX... What does it mean?

Definition of the IP

Internet Protocol allows you to assign a unique address to each computer device (or terminal) connected to the Internet (your computer, smartphone, etc.). 

This IP address ensures the proper routing of communications, the transfer of data, known as "packet data switching".
IP networks can be wired (cable/ADSL/optical fiber) or wireless (satellite, WiFi, GSM, UMTS or LTE).

With the end of the switched network, telephone operators will soon only use IP infrastructure for their voice services. 

VoIP and IP telephony

VoIP stands for Voice Over Internet Protocol. In a simpler way: it's Skype, WhatsApp, Viber, OVH Telecom, etc. We communicate by voice via the Internet, from any medium (tablet, computer, telephone). Telephony is managed from a web interface.

WiFi VoIP has quickly found its audience with individuals, but it is taking longer to democratize in companies. Many companies now use it for their internal voice communications, which are free and unlimited. Some intend to implement it as part of unified communication. 

IP Telephony stands for Internet Protocol Telephony. It's the same, but it only concerns communications via WiFi from phone to phone. It uses the IPBX system because it operates the internal network of a company that connects IP phones to each other. 

Definition of the IPBX system (or PABX-IP)

It stands for Internet Protocol Branch eXchange (or private switchboard using Internet protocol). 

IP - PBX system Setup

Unlike the old PBX system, which will disappear eventually, the company can easily add and configure new lines from a computer interface.

Hosting is done on a dedicated server, but not necessarily in the cloud.

The fact that not all operators have yet switched to the cloud is partly explained by the drop in revenue it generates: there is no longer any telephone equipment to sell or maintain.

Definition of the Centrex IP system

It is an external switchboard, with an IPBX installation, but hosted by an operator that shares its telephone infrastructure, in cloud mode, between several customers. As the standard is external, the company just has to buy IP telephony sets.

It is for security reasons (the problem of data leakage hosted on these shared servers) that some solutions using the Centrex system are evolving towards dedicated SaaS platforms (Software as a Service, in the cloud). Skype is one of them.

The Centrex IP is suitable for a small to medium-sized structures and businesses, the number of connected workstations being limited to around twenty.

The virtualized IPBX (or Virtual PBX for Virtual Protocol Branch eXchange)

It is a private external switchboard, 100% cloud, mixed between the IPBX (dedicated server hosting) and the Centrex platform (no telephone infrastructure to manage). It is considered more secure than Centrex IP, which allows all communications to pass through a single location.

This is the system offered by many software packages in SaaS mode because it allows personalized value-added services: UcaaS (Unified Communications as a Service). The services included are:

  • Shared agendas,
  • Instant messaging,
  • CRM integration,
  • Audio and video conferencing, etc.

Telephony in the cloud

The virtual IPBX is the cloud telephony system of the future. Let's look in more detail at the interest of this new trend.

#1 Mobility

Cloud telephony allows for connection to telephone service from anywhere at anytime, as long as there is Internet

Cloud telephony is particularly suitable for multi-site, even international companies:

  • Connection to telephone services from anywhere, 24/7, as long as there is Internet access,
  • Unified communication solutions that are identical or compatible worldwide.

#2 Cost savings

  • Invoicing by use or by fixed price,
  • Savings on communication costs (same regardless of distance),
  • Easy installation, with no maintenance costs.

#3 Adaptability

  • For all types of structures, of all sizes,
  • For internal use or roaming,
  • Differentiation of professional activity from personal life, from the same telephone, for self-employed entrepreneurs,
  • Keeping the number in travel, in mobility (associated with the person and no longer with a line).

#4 Safety and security

  • Data preservation through replication and backup systems,
  • Confidentiality, security (contractual): restriction of the operator's access to identifiers, passwords, CRM.

#5 Other benefits include

  • Bandwidth optimization,
  • A multitude of additional services offered by software in SaaS mode:
    • Document sharing
    • Collaborative meeting
    • Audio and video conferencing, etc.
  • Scalable applications through updates.

💡 Tip: The local network must be compatible with IP telephony. An audit is preferable before the implementation of a hosted telephony.
