    1. Different approaches of the telephony over ip

    1.1 The Telephony over IP (ToIP)

    Unlike the VoIP (Voice over IP) that is only the delivery of telephonys voice from one network to another (whether public or private, internal or external), the ToIP (Telephony over IP) in over what VoIP, provides services and features on the transport of voice.

    IP telephony can be done via IP Phones (phones running on the IP protocol) or computer (thanks to softphones).

    We will see that IP telephony can be used in addition to traditional business telephony via a gateway, or "Full-IP"; what interests us particularly in this document.

    Note :

    The use of a VoIP gateway, allows to get his voice flow to an operator in VoIP (DSL or optical) rather than by a conventional connection (multichannel) rent from a service provider ; this technique saves on cost of routing voice via an IP link properly sized (and have a classic or mobile backup solution by reducing the number of leased channels, to be used only in case of failure in degraded mode).

    1.2 The Full-IP

    What we call the "Full-IP" on IP telephony, as stated above, is the fact of using the telephony features and services as well as IP transit at all; it is both the combination of telephony and voice over IP.

    The "Full-IP" can be used only internally to a single-site enterprise or a multi-site or in course of a communication with the outside world. Let's see two technologies of "All-IP" today in business. Note :

    In the following paper we will only use that IP telephony term to talk about these two technologies.

    2. Telephony over IP ; the solutions

    2.1 The IPBX

    ToIP based IPBX (IP PBX) involves the installation of a telephony server within the company (currently called IPBX or PBX).

    This phone technology, allows to the company a flexibility in the choice of its internal architecture, but especially for the external the company can choose their telecom operator for connection to the traditional PSTN or IP network, to change easily, and easily back-up its solution. The telephony server can also easily connect remote sites with a single bond. It is a solution that brings greater independence regarding access operators and providers.

    - Schema 1 -

    Overnight (with a delay of a few days anyway), it is possible for a company to change operator for the transit of its telephony, or have a back-up solution on the site (2nd link relief from a different operator) is an important advantage of this telephony solution "Full-IP" internal to the company.

    Cons of this solutions are :

    The hosting of the solution on the companys infrastructure. The management of the solution* The full cost of the solution if you have a big infrastructure;

    monthly or annual maintenance fees if proprietary solution, and all costs associated with the management.

    *Focus on managing a PBX solution :

    Whether you choose a proprietary solution IPBX (Alcatel, Cisco, Mitel, Aastra, Panasonic ...) or free (Asterisk, SIPX, Saturn, ...), there are associated costs with configuring Services, Maintenance (IP- Phones, connect, add / delete / move a user, ...).

    When the solution is proprietary, even as it is often the cost of licenses by IP-Phones and/or annual maintenance, ... :

    - When adding/deleting a post sometimes require a technician to a service company authorized to configure of the solution.

    - When installing/uninstalling/ also move the solution.

    When the solution is free, must implement a solution yourself or hire a professional service provider/expert consultant ? In either case, there is a cost in human resource internal or external services expenses. Also, for structures on a human scale (less than 50 users), these costs are often included in maintenance contracts or in the monthly total amount of the contract (installation + commissioning + packages ...).
