The traditional recording method employs high-impedance line(“T” type) to connect recording systems with analog or digital extension / E1 / SS7 lines. It records call data by using a conjunction of recording boards and servers.
The high-performance recording boards record calls on the line in the server by means of line shunting. Thanks to professional recording boards and a unique voice resource distribution method, voice resource compression on each line is processed independently with DSP resources. CPU resources are not consumed, and recording stability is effectively guaranteed.
