Desktop Monitoring
Desktop monitoring requires more bandwidth than does server monitoring (using a
VoIP Monitor Service). Please refer to the best practices document, Cisco Agent
Desktop Bandwidth Requirements, for more information.

Recording & Playback Service
The Recording & Playback Service stores recorded conversations and makes them
available to the Supervisor Record Viewer application.
available to the Supervisor Record Viewer application.
A co-resident Recording & Playback Service can support up to 32 simultaneous
recordings. A dedicated Recording & Playback Service can support up to 80
simultaneous recordings (this option is available in the Premium version only). The
capacity of the Recording & Playback Service is not dependent on the CODEC used.

Example
Assumptions:
Assumptions:
■
10-hour working day
■
20 calls per agent per hour (average handle time [AHT] 180 seconds: 120
seconds per call with a 60-second wrapup)
seconds per call with a 60-second wrapup)
■
8% of calls, or 16 call per agent per day, are recorded
■
service level of 90% of calls answered in 10 seconds
■
Agent:supervisor ratio is 10:1
Agent resources are calculated using an Erlang C computation.
Recording resources are calculated using the above assumptions and an Erlang B
computation, assuming 0.001 blockage. In the case of recording, there will not be
actual blockage, instead, an additional recording resource will be used.

A formula for simultaneous recording resources needed in the busy hour based on
percentage of calls monitored can be calculated as follows:
percentage of calls monitored can be calculated as follows:
(BHCC = busy hour call completion)
In a contact center with 1000 calls per hour and an 8% call recording rate, the
