Nortel Contact Recording and Quality Monitoring

Nortel Contact Recording and Quality Monitoring
Technical Brief
Nortel Contact Recording and Quality Monitoring
Nortel Contact Recording and Quality
Monitoring are robust, embedded
recording solutions designed specifically
to eliminate middleware, proprietary
servers and custom integration points.
Working in IP, traditional (TDM) and
hybrid TDM/IP environments, these are
future-proof solutions that reduce your
Total Cost of Ownership (TCO) while
delivering productivity and profitability
Nortel Contact Recording solutions
provide conversation recording in
Nortel Communication Server (CS)
1000 enterprise and Contact Center
environments. IP-based Nortel Contact
Recording solutions utilize the Nortelexclusive Duplicate Media Stream
(DMS) technique for the most tightly
integrated IP call recording in the
industry. This technique provides a
speech path separate from the main
conversation dedicated exclusively to
conversation recording, thus ensuring
your conversation is captured. TDMbased Nortel Contact Recording utilizes
Ai-Logix tap cards to capture conversations. Nortel Contact Recording offers
three methods of call recording:
> Recording All Calls — ‘Logging’
> Recording Percentage of All Calls —
> Contact Recording Desktop —
‘Ad Hoc’
Nortel Quality Monitoring solutions
provide video screen capture of agent
workstation and other activity including
agent scorecard creation, agent scoring
and evaluation, and report generation in
Communication Server 1000 Contact
Center environments. Nortel Quality
Monitoring may also utilize Call
Recording Cards to provide ‘live monitoring’ capability in TDM or hybrid
IP/TDM configurations when a Quality
Monitoring-only, cost-sensitive implementation is desired.
Nortel Contact Recording
and Quality Monitoring
solutions are “must-have”
solutions for companies that
need recording for:
> Compliance with regulatory
> Risk reduction and dispute
> Operations optimization
> Agent interaction analysis
> Employee development
> Customer relationship
Nortel Contact Recording TDM Slave
— This component provides recording
of digital or analog phones or T1/E1
trunks (with or without ISDN PRI)
when the capacity of the Recording
Master is exceeded. A Slave recorder can
record up to 360 concurrent channels
per server, creating a solution that scales
well to fit any customer’s needs.
Solution components
Nortel Contact Recording — Nortel
Contact Recording supports both IP
and traditional telephony (TDM)
equipment and scales from a single
server solution to large enterprise
deployments with many thousands
of channels.
Nortel Contact Recording Master —
This is the server between the recorders
and Contact Center Manager Server
that utilizes the Meridian Link Services
(MLS) interface, delivering the native
Computer Telephony Integration (CTI)
that distinguishes this embedded solution from all third-party recording products. The MLS interface links the
Contact Recording solution, the Quality
Monitoring solution and the Call
Recording Cards to the Contact Center
Manager Server via the MLS interface.
One Master server is required for each
Contact Recording solution. The Nortel
Contact Recording Master is configurable for IP or TDM environments.
Nortel Contact Recording IP Slave —
This component provides IP recording
when the capacity of the Nortel Contact
Recording Master is exceeded. Multiple
slave Contact Recording solutions can
be deployed, creating a solution that
scales well to fit any customer’s needs.
Nortel Contact Recording Central
Search and Replay — This is the
central repository to search and play
back all recorded calls across a CRQM
configuration. It contains the MetaData
(CLID, time of call, duration of call,
etc.) associated with each call. Central
Search and Replay allows up to 10
simultaneous users to search and replay
calls on a PC via a browser interface and
can be deployed across the WAN. This
enables either local or remote management capabilities.
Nortel Contact Recording Archive
Manager — Archive Manager selectively archives calls (based on customer
requirements) to a Redundant Array
Independent Disks (RAID)
Configuration, Digital Versatile Disk
(DVD), Blu-Ray DVD (BRD) or HDDVD, or Storage Area Network (SAN)
where they can be readily accessed for
historical retrieval. It is used by
customers who have many recording
Figure 1. IP environment
servers or who want immediate access to
historical recordings. Archive Manager
resides on a dedicated, standalone server.
Nortel Quality Monitoring — As a
complement to Contact Recording,
Nortel Quality Monitoring supports
both IP and TDM environments.
Quality Monitoring is based on the
same recording technology as Contact
Recording, but is designed for use in
contact center environments. It provides
call and screen recording of up to 120
concurrent selected recordings and
allows playback and evaluation of
those recordings.
Call Recording Card — Deployed in
Quality Monitoring-only scenarios, this
card is installed in the Communication
Server 1000 Media Gateway to support
cost-effective recording for Quality
Monitoring in TDM or hybrid
TDM/IP environments. The Call
Recording Card is based on the Media
Card architecture (similar to other
applications such as IP Line, IP Trunk,
Agent Greeting and Remote Agent
Observe). It has a total of 32 ports,
16 of which are used for observation/
recording and 16 of which are used for
live monitoring. Up to 8 Call Recording
Cards may be deployed in the same
environment for simultaneous monitoring of up to 120 concurrent sessions.

Ai-Logix Card — This card may be
used for TDM or hybrid TDM/IP environments to deliver either extension side
or trunk side recording. (Optionally,
Meridian Link Services can be used if
more tagging information is needed for
recordings.) There are three versions of
the card:
> Digital Ai-Logix card — For digital
extension side recording with digital
telsets when extension-to-extension
conversations need to be recorded
> Analog Ai-Logix card — For analog
extension side recording with analog
telsets when extension-to-extension
conversations need to be recorded
> Trunk Ai-Logix card — For econom-
ical trunk side recording when extension-to-extension conversations do
not need to be recorded
Trunk side recording requires the
Meridian Link Services interface to
provide correlation between the trunk
channel and the telephone to be recorded.
Extension side recording has two options:
> Recording with Ai-Logix cards
extract signaling information from
the D-channel which can be used for
tagging calls.
> Recording with Meridian Link
Services interface provides a number of
additional tagging fields which can be
used for search and replay purposes.
> Phase 2 Nortel IP sets
Note that one AST ISM is required for
each telephone to be recorded (i.e., each
device to be monitored via MLS).

Storage requirements
Storage needs vary by company based
on regulatory requirements and operational practices and the audio standards
Recordings are stored in industry standard “.wav” file format using one or
more of the following CODEC audio
> G.711 PCM A- or µ-law (64 kbps)
> G.726 ADPCM (16 kbps)
> G.729A (8 kbps)
Server requirements
Industry-standard Intel x86 32-bit
servers are supported for Nortel Contact
Recording and Quality Monitoring.
Storage format depends on the type of
recording and the format the audio was
originally received in.
Recordings provided by Nortel Contact
Recording are stored in G.726 compressed form or as a pair of G.729A
files if high volumes of recordings need
to be stored on the available disk space.
RAID arrays or redundant Storage
Attached Network (SAN) devices for
online storage of recordings on the
recorder platform are recommended.
Available disk storage space is managed
as a circular buffer providing instant
access to the most recent recordings.
For longer term retention of recordings,
two options are available:
> A DVD+RW drive can be connected
to the recorder. All recordings made
on the recorder are automatically
archived to the removable media,
which can be remotely stored in a safe
location for historical preservation.
In all cases, the system automatically
notes the location of the additional
copies of the recordings such that when
a user wishes to replay a call that is no
longer in local online (disk) storage,
they will be prompted to insert the
appropriate removable media.
By deploying Contact Recording and
Quality Monitoring, businesses have
the ability to record interactions and
monitor the quality of those interactions. This in turn can provide more
efficient and exceptional customer
service. For more information on
Nortel Contact Recording and Quality
Monitoring, please contact your Nortel
representative or visit us on the Web at or
> Archive Manager can be added to
this system for selective archival of
recordings to multiple destinations
(e.g., RAID, DVD, BRD, HD-DVD,
SAN, etc.).
