Engineering SESTREAM engineers develop data-processing solutions for your critical needs of quality and safety and requiring a fast answer.
The Open source software Open source software represents the alternative to the proprietary software. A community of data processing specialists who guarantee its reliability and its perpetuity carry it. This is different from freeware because the source codes are available, which makes it possible to modify it. To be able to use the free software it is necessary to accept the license of the software that defines three freedoms: • freedom to carry out the program, for all the uses and all the users whatever their number. • freedom to study the operation of the program, and to adapt it to its needs • freedom to modify and improve the program
Use a simple and economic methodology in order to give the best answer to your expectations
S
ESTREAM created a simple methodology to
offer to you a personalized service of quality. However, this methodology is not exclusive and can be adapted to your particular needs.
Our methodology Analyze your network: to better understand the organization and the operation of your information system. Analyze your needs: to highlight the critical needs to answer your expectations as well as possible. Find out a solution: to choose a solution adapted to your needs. Adapt and install the solution: to customize the selected solution when necessary to answer your needs in the context of your information system.
Measure the quality of service: to carry out tests to determine which satisfaction degree the solution brings to the problem arising. Put in place a user guide: in order to make you profit from a qualification level on the solution suggested. Teach the technology: to learn operation from the system and thus to maintain an independence with respect to technology. Propose technological improvements: to advise possible future modifications based on the technological innovations.

Setting up a VoIP network SESTREAM, thanks to the technology of Open source software (Asterisk, Linux), proposes the setting up of your VoIP network so that you communicate free between and within your sites. VoIP technology can be applied to two levels: To connect employees inside the same site or to an other site via a computer, an IP telephone or an analogical telephone equipped with an adapter. To communicate towards the public network. Example of a VoIP network in a mono-site company connected to the public network: Ethernet Network Public Telephony Network
Computer with VoIP software Ethernet Network IP telephone
IP/PBX Astérisk
Ethernet Network Adapter for Analogical analogical telephone telephone
OpenVPN OpenVPN is a complete VPN solution (server and client). It makes it possible to create VPN connections thanks to the creation of safe tunnels. The safety is ensured by multiple encryption algorithms combined with the OpenSSL bookshop and on various methods of authentication (coding by pre-divided key and public key). OpenVPN is able to encapsulate any IP network • which uses dynamic protocols at the two ends • which uses NAT OpenVPN also makes it possible to set up a system of load balancing or a compression of the connection, which adapts in real time in order to optimize the flow. The administration functionalities included make it possible to remotely manage and control the server thanks to a suitable interface. .
Asterisk The Open source software Asterisk was created in 1999 per Mark Spencer. It transforms a computer into a PABX, which inter-connects networks of voice over IP based on several protocols (SIP, H.323, MGCP, etc) and/or with the traditional telephony network via telephone interface boards. Asterisk offers all the functions of a PBX and its services associated: • conference call • interactive answering machine • call standby • call forwarding • vocal emails • call waiting • and new functionalities resulting from the IP/PBX (for instance, the Web fax, the Click and Dial, the mobility, etc)
Setting up a VPN SESTREAM thanks to the technology of the Open source software (OpenVPN, Linux) proposes a free VPN network allowing exchange license of data between your sites or towards a nomadic station.
