Voice Over Internet Protocol is a technology that involves the transmission of voice communication and other multimedia sessions over Internet Protocol (IP) networks. Fax, SMS, voice messaging applications can also be transported via VoIP channels. VoIP services are usually much cheaper than traditional telephone services.
Traffic is the summation of the VoIP calls and other data, received and delivered via the Internet.
VoIP termination is a process of phone calls routing through the IP network to the final recipient. The call is routed from one carrier (VoIP provider or Telephone Company) to another until it has been received by the called party. VoIP termination is also stated as call termination or VoIP wholesale termination.
ASR and ACD are key quality metrics for VoIP providers. ASR (Answer-Seizure Ratio) means the ratio of successfully-connected calls to the total call attempts. ACD (Average Call Duration) shows the average duration of routed calls.
CLI means Caller Line Identification. It is a type of VoIP route that transfers Caller ID, making it visible to the recipient of the call. Commonly CLI routes are good-quality routes.
CC traffic (Call Centre traffic) has its own specific characteristics compared to regular traffic. CC traffic is usually marked by large Calls per Second (CPS) and low Average Call Duration (ACD) rates.
In contrast to traditional person-to-person messaging (P2P), A2P (application-to-person messaging) is any kind of traffic, where a person receives messages from an application.
