1.What is VoIP?
VoIP (or Voice over Internet Protocol) is a new way to make and receive telephone calls. You use your high speed Internet connection (either DSL or cable) instead of a regular phone line.VoIP service provider converts voice signals to data and sends it through your high-speed Internet connection, just like email. Calls ring on the other end – even if you are calling someone with a regular phone – and sound just like regular phone calls. The big advantage with VoIP is that all your calls cost less and you get more features without paying extra. Compared to regular phone lines, VoIP technology and the Internet are cheaper and more efficient for transporting phone calls and delivering features. The savings by using the Internet and VoIP technology are passed on to you. You will not lose anything except high monthly phone bills.
2.How does VoIP work?
VoIP service provider takes voice signals from your standard corded or cordless touchtone phone and converts them to data, using a special device called a Terminal Adapter. Calls are then sent over your high speed DSL or cable connection to the Internet. If both you and another person have the same VoIP company’s service, calls to each other are free because they only go over the Internet. If you are calling someone (or someone is calling you) and they only have a regular phone line you will still save money. Calls will go over the Internet, but they connect with regular phone lines – seamlessly. You will not know the difference.
3.What is SIP?
SIP, short for Session Initiation Protocol is an IP telephony signaling protocol used to establish, modify and terminate VOIP telephone calls. SIP was developed by the IETF and published as RFC 3261.SIP describes the communication needed to establish a phone call. The details are then further described in the SDP protocol.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.
4.What is DID?
DID – Direct Inward Dialing (also called DDI in Europe) is a feature offered by telephone companies for use with their customers’ PABX system, whereby the telephone company (telco) allocates a range of numbers associated with one or more phone lines.Its purpose is to allow a company to assign a personal number to each employee, without requiring a separate phone line for each. That way, telephony traffic can be split up and managed more easily.DID requires that you purchase an ISDN or Digital line and ask the telephone company to assign a range of numbers. You then need DID capable equipment at your premises which consists of BRI, E1 or T1 cards or gateways.
5.What is Access Number?
Access Number is a local number for you. You call a local number instead of the international number of your loved one. Eg. You are based in the UK (Party A with a +44xxxxxxx) and has a loved one in the Philippines (Party B with a +63917xxxxxxx). When you register to Accsee Number providers, Party B will be assigned a +44xxxxxxx number. Whenever you need to call Party B, you will dial a UK/+44xxxxxxx number. It is fast and easy since you won’t have to dial country codes and access codes whenever you make long distance calls.
