The business model in the case of relations between international operators is different than on the domestic market. The parameters differing from national ones, account for strength and interest in cooperation. Before the transit of traffic between operators takes place, the business case is the key, during which destinations, volumes and rates are discussed.
Subsequent activities include testing of contact points and billing test, i.e. the billing tests, whose task is to check the correctness of billing, settlements and calculation of charges.
Significant quality parameters in the implementation of voice transit are:
- ACD (Average Call Duration), which is the average duration of VoIP calls, considered as a parameter indicating the quality of traffic of a given operator.
- ASR (Answer-Seizure Ratio), i.e. the ratio of successful calls to call attempts (also known as “call performance ratio”).
- CLI (Calling Line Identification), or identification of the caller’s number (initiating the call).
- nCLI lub Non CLI (non Calling Line Identification), i.e. no identification of the caller’s number (initiating the call).
At the level of traffic exchange, the following technical parameters and quality tests are important:
- PING (Packet Internet Groper), also known as sonar for diagnosing the speed of network connections.
- FAS (False Answer Supervision) is commonly referred to as the supervision of false telephone responses. For an ordinary user, this means incorrect calculation of connection fees: the billing starts earlier than the called party answers the call.
- Direct routing, i.e. direct connections between operators from own networks and numbering.
International standard codecs used by operators around the world are used in LoVo for transit of international calls.
