V1 VoIP Glossary of VoIP Terms

ACD (Average Call Duration)
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.
ACD is a quality metric used by telephony providers to show the average length of a call made over their network. V1 VoIP 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 low ASR 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. A high ASR ndicates a reliable network, since most calls that are attempted are answered.
Call Termination
Call termination services allow other carriers and telephony companies to pass their VoIP calls onto the PSTN 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.
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. V1 VoIP offers resellers 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. V1 VoIP provides services that allow VoIP resellers to terminate calls onto the PSTN.
