The IP Call Recording enhancement enables the following types of
recording:
•
•
The IP Call Recording is initiated by the CR. A Start Recording Request
message is sent that contains the User ID to be recorded and the IP
addresses and port information of where the duplicate media stream is to
be sent.
In LD 11, the Class of Service ICRA/ICRD (IP Call Recording Allowed/IP
Call Recording denied) is available for the IP Phones that support IP Call
Recording. The default is ICRD. See
Warning tones
If Recording Warning Tone is required, this tone can be turned on or off on
the Call Server using the existing UNIStim message Stream Based Tone on
or off. The message requires the predefined parameters for the tone, such
as tone ID, frequency and volume.
Bandwidth requirements
The use of IP Call Recording doubles the bandwidth requirements of the call.
For example, in a call using the G.711 codec, one voice packet data
stream requires approximately 80 kb/s. As the IP Call Recorder uses two
separate streams for the in/out calls, there are four streams requiring a total

Bulk Call Recording – All calls are automatically recorded for a particular
IP Phone. The Call Recording application issues a Start Recording
Request message for the User ID, and all calls are recorded until the
Call Recorder application issues a Stop Recording Request.
Quality Monitor Recording – The Call Recorder records conversation
for a particular call. The Call Recording application can monitor the
Call Recording application (CR) data such as Calling Line ID (CLID) or
Automatic Number Identification (ANI) to determine if it needs to record
a specific call. The Call Recording application issues a Start/Stop
Recording Request to the User ID for only the duration of the specific
call. Quality monitor recording enables manual recording of individual
calls with the following options:
— Call recording can be started or stopped at any time during a call.
— Call recording can also be paused and restarted repeatedly during a
call, enabling excerpts from a conversation to be recorded.
— Call recording can begin retroactively. At any time during the
conversation, the entire call can be saved; it is not necessary to start
recording when the call begins.
— Call recording can be configured to maintain ACD Emergency key
functionality.
