Latency is a major annoyance that can interrupt important conversations and cause irritation between callers. Latency, or more famously known as ‘lag’, is the time delay from when you speak to when the other person hears your voice. A common cause of poor VoIP (Voice over Internet Protocol) calls, high latency value can lead to great difficulty in conducting conversations and cause frustration.
Phone calls are normally made between two remote locations, so there will always be some natural delay. More extreme delays increase the conversational challenge. Latency can be caused by a number of factors in the call path, including the number of network hops and the chain of hardware components that ultimately link the call.
