Glossary of voip terms
VoIP Advantages
One advantage of VoIP is "portability." Your call can be easily forwarded to anywhere, a cell phone, a hotel room, etc. Another plus is that you can have multiple phone numbers within an area code, which is costly with landlines. Other benefits include video conferencing and real-time collaboration.If you do want to try out VoIP then check with others you may know who have it. Choose a reputable provider that can provide customer support and is responsive to your questions. And make sure that the service is good in your neighborhood because like cell service, location is important.
Large companies are bundling VoIP and Internet or telephone or cell service. You might use your cell phone as your primary line and make long-distance calls over the Internet.
Whatever you do, have fun and good luck.

Peer-to-Peer (P2P):
The term peer-to-peer is used to indicate a form of computing where two or more than two users can share files or CPU power. They can even transmit real time data such as telephony traffic on their highly ad hoc networks. Interestingly, the peer-to-peer network does not work on the traditional client-server model but on equal peer nodes that work both as "clients" and "servers" to other nodes on the network.
VOIP PBX:
VoIP PBX, which stands for Voice over Internet Protocol Private Branch eXchange, is a telephone switch that converts IP phone calls into traditional circuit-switched TDM connections. It also supports traditional analog and digital telephones.
ACD (Average Call Duration)
ACD is a quality metric used by telephony providers to show the average length of a call made over their network. TATAMAX has a high ACD which suggests that few calls are dropped or abandoned due to quality issues.
ASR (Answer / Seizure Ratio)
The Answer / Seizure Ratio is a metric used to measure the quality of a telephony company's network. It is calculated by dividing the number of successfully answered calls by the total number of calls attempted.
A high ASR like TATAMAX's indicates a reliable network, since most calls that are attempted are answered. A lowASR may suggest a poor quality network, though it can be heavily influenced by user behavior since busy signals and unanswered or rejected calls count as failures.
Call Termination
TATAMAX's call termination services allow other carriers and telephony companies to pass their VoIP calls onto thePSTN so that they can be answered over a traditional phone line.
Codec
A codec is used to compress and decompress an audio signal before transmitting it over the network. There are a number of different speech codecs used by VoIP carriers. TATAMAX supports the G.729a and G.723 codecs for all of our routes, as well as G.711u, G.711a, and G.726 for most.
PDD (Post-Dial Delay)
Post-Dial Delay is the time it takes to receive feedback after a user has finished dialling. This feedback can be in the form of a dial tone, a recorded announcement, or the call being abandoned.
TATAMAX has a low PDD which gives an improved user experience. Consumers are generally used to the PSTN's short PDD and often react negatively when there is a long pause after dialling.
PSTN (Public Switched Telephone Network)
The PSTN is the network that makes up the world's traditional telephone systems. TATAMAX provides services that allow VoIP companies to terminate calls onto the PSTN.
VoIP (Voice over Internet Protocol)
VoIP is a specialised protocol used to transmit voice data over the Internet. It is also commonly used to refer to the act of transmitting voice, and the many related services that have built up around it.
A VoIP provider is a company like TATAMAX, that is set up to sell consumer or business-to-business telephony services-we offer our service to carriers, small businesses, callshops, resellers and other VOIP service providers.
