Your VoIP Questions Answered


What is VoIP?

VoIP is a category of hardware and software that enables people to use the Internet as the transmission medium for telephone calls by sending voice data in packets using IP rather than by traditional circuit transmissions of the PSTN. VoIP is usually much less expensive than PSTN.

VoIP stands for Voice over Internet Protocol and it refers to the diffusion of voice traffic over internet-based networks. VoIP is widely used to cut the cost of traditional PSTN and some of its major benefits are:
* More than one phone call on same line.
* Advance features, such as call forwarding, caller ID or automatic redialing, are simple and usually free.
* Communications can be secured with encryption

What is a SIP server?

A SIP server is the main component of an hosted PBX, dealing with the setup of all SIP calls in the network. A SIP server is also referred to as a SIP Proxy or a Registrar. An example of a SIP server is our BioVoIP

What are SIP Phones?

SIP phones are the same as VoIP or soft phones and are used for VoIP (Voice over Interver Protocol) calls. There are two types of SIP phones: Hardphone (resembles common phone) Softphone (computer – software phone) BioVoIP can be used with virtually all SIP phones on the market.

What is SIP?

SIP stands for Session Initiation Protocol. It is an IP telephony signaling protocol used to establish, modify and terminate VoIP telephone calls. SIP has taken the VoIP world by storm. The protocol resembles the HTTP protocol, is text based, and very open and flexible. It has therefore largely replaced the H323 standard.

How secure is VoIP?

VoIP can be deployed to use industry standard high encryption technologies (SSL and VPN).

How good is a VoIP sound quality?

The quality achieved is excellent. We use the G729 audio codec which is not very bandwidth intensive thus ensuring good quality on even low bandwidth connections. i.e. mobile connections .

Echo cancellation is the process of removing echo from a voice communication in order to improve the voice call quality. Echo cancellation is often needed because speech compression techniques and packet processing delays generate echo. There are 2 types of echo: acoustic echo and hybrid echo. Echo cancellation not only improves quality but it also reduces bandwidth consumption because of its silence suppression technique.

RTP stands for Real Time Transport Protocol. It defines a standard packet format for delivering audio and video over the internet.

What is RTCP?

What is a STUN Server?

STUN stands for Simple Traversal of User Datagram Protocol Through Network Address Translators. The STUN server allows clients to find out their public address, the type of NAT they are behind, and the internet side port associated by the NAT with a particular local port. This information is used to set up communication between the client and the VoIP provider and to establish a call.

What does ENUM mean?

ENUM stands for Telephone Number Mapping. The idea behind ENUM is to be reachable anywhere in the world – with the same number – and via the best and cheapest route. ENUM takes a phone number and links it to an internet address which is published in the DNS system. The owner of an ENUM number can thus publish where a call should be routed to via a DNS entry. Different routes can be defined for different types of calls.
