A quick overview of some of the terms and acronyms used in IP PBX.Don't worry though we at London computer Centre are here to help and can explain to you what you need to know.
What is VOIP?
VOIP stands for Voice Over Internet Protocol - It is a standard of voice communication over networks such as your office intranet or the internet. VOIP users, amongst other things,can take advantage of these networks to make cheap calls.
What is IP PBX?
A PBX is a telephone system that manages telephones in your premises and will act as the gateway to external voice networks. A switch or router directs incoming packets to the appropriate data network.i.e using one for voice and one for other data.
An IP PBX can be used with IP phones ( 'internet phones' ), softphones, and traditional phones with adapters.
VOIP GSM Gateway?
A VoIP GSM (Global System for Mobile communications) Gateway enables direct connection between IP, digital, analog and GSM networks. With these devices (fixed cellular/mobile terminals) companies can significantly reduce the money they spend on telephony.
Why should I buy a IP PBX?
To save money on calls and line rental, and to streamline your business's phone needs.
Is VOIP Secure?
Was my old phone system secure? In a word No. Traditional phone lines can be tapped. A VOIP IP PBX system can be set up securely and VoIP phones' use of encryption today provides better privacy protection than most legacy phone systems.
What are FXS and FXO (in case you are asking)?
These are the ports used by analogue phone lines. The (FXS) Foreign eXchange Station is the socket that provides power, ring tone and battery current to the user device e.g. phone, fax, or modem. The FXO (Foreign eXchange office) is the interface that receives the power and signals.i.e. the plug on the phone.
To connect an analog phone to a computer an FXS interface is needed to convert the signal form analog to digital.
If you want to connect a line to your computer so that it can make and answer calls on your analog telephone line, you need to add an FXO interface to convert the signal from digital to analog.An FXO adapter can be used to connect an IP-PBX in a LAN environment to regular analog phone lines.
SIP Trunks are alternatives to traditional ISDN and Analogue trunks as they operate using Internet connections rather than physical lines
thus as the call is placed over the Internet it is possible to make long distance, even international calls at a fraction of the price.
Session Initiation Protocol (SIP)
This is a protocol used to transmit data such as VOIP calls, video-conferencing, instant messaging and file transfers.
