Ways
to record your customer interactions
Passive Mode(Automatic Recording):​
-
In TDM environment, Lockstone's recorder (LAS as short in the following chapters) captures voice by tapping on telephone wire with high impedance interface card, and collect call details information through D-Channel (Digital) or FSK (Analog). Call recording will be triggered and termination by on/off hook events automatically
-
In VoIP environment, LAS passively sniffers RTP packet through Mirroring Point on network switch and decodes the CTI or SIP signaling from which the phone’s on/off hook events will be extracted. In order to make sense of packets being received, C is able to map the voice data steams to the physical agents’ stations or extensions by using IP address (Static) or MAC address (DHCP).
Active Mode(Application Invoked Recording):​
-
In active mode, LAS interacts with CTI server, to invoke the recording session for active call through all kinds of SDK such as TAPI/JTAPI, TSAPI and SRC etc.
-
Recording in active mode might be more flexible compared with Passive mode (Automatic Recording), you are able to perform selective recording, recording load-balance and redundancy easily.
-
However, it needs additional telephone lines (or license)which will be used to connect the call recording equipment to the telephony system
