Several solutions exist to make Voice over IP. Either with proprietary solutions and infrastructure based on a service provider server such as Skype or Yahoo! Messenger software. Other solutions such as NetMeeting or KPhone, can operate in a peer-to-peer network or connect via standard protocols independent phone infrastructure. Finally, some manufacturers offer solutions such as IP PBX Aastra, Cisco, Alcatel, Wildix, Sipleo3 or free Asterisk solution.
The parameters required include:
Owner network name, password, no such thing, APN (mobile)
of Voip Service: name, password, IP / domain FQNDN, stun server, Proxy outBoound
VoIP equipment is more directly compatible with Wi-Fi phones all in one, or many “VoIP gateways” that allow you to connect an old post of traditional phone service.
Some materials are linked in their operation with proprietary solutions like Skype, while others are based on the open SIP protocol, providing compatibility with a variety of VoIP services.
There are PCI interface cards (eg Digium) which allow PBX (such as Asterisk) software to connect to one or more analog lines (classic). VoIP for better compatibility, they must comply with TIA / EIA standards, ISO / IEC and CENELEC in the cabling Ortronics fiber or copper.
VoIP should be improved by IPv6 when generalized. The quality of service built into its design allows to independently manage various streams such as voix4, Internet browsing (including downloads that loom large bandwidth).
In this way, the voice quality should be optimum and of consistent quality.
