Quality in SCCP and Session Initiation Protocol (SIP) mode. (You must have new firmware;
the firmware can be downloaded from Cisco Unified Communications Manager 4.2 or 5.x.)

Score is sent at the end of the call by using CMRs
Unlike Cisco 1040-based call quality reporting, Cisco Voice Transmission Quality–based call quality
is reported at the end of the call. You can use Cisco Voice Transmission Quality–based reporting if
you prefer not to have call quality reporting as the call progresses. Also, the Cisco Voice
Transmission Quality feature is inherent to Cisco Unified Communications Manager 4.2 and later.
Therefore, if you do not want to invest in a Cisco 1040, Cisco Voice Transmission Quality–based
call quality still provides MOSs to estimate user experience.

Scalability
Service Monitor scalability is dependent on the estimated call rates generated in the network. The
call volume supported by a fully loaded Service Monitor 201 system with various scenarios is given
in Table 1.

Preparing the Server for Service Monitor
This section describes how to prepare your server for Service Monitor installation
Operating System and Server
Service Monitor is supported on Windows 2003 Server SP1/ SP2—Standard Edition and Windows
2003 Server SP1/ SP2—Enterprise Edition. No other operating systems are supported. It is
recommended that software other than the operating system and antivirus software not be installed
on this computer system.

Server suggestions:
●
For a small network (under 5000 phones), Serial ATA (SATA) disks are required.
●
For a medium network (5000 to 15,000 phones), SCSI disks are required (suggestion: MCS
7845-I1 or MCS 7845-H1 comes with SCSI).
7845-I1 or MCS 7845-H1 comes with SCSI).
●
For networks with more than 15,000 phones, Serial Attached SCSI (SAS) disks are required
(suggestion: MCS 7845-I2 or MCS 7845-H2 comes with SAS).
