● 

Cisco Voice Transmission Quality is supported from Cisco Unified Communications 
Manager 4.2 or later versions. 

● 

Cisco 7906, 7911, 7931, 7921, 7962-G, 7962-G/GE, 7942-G, 7942-G/GE, 7972-G/GE, 
7940, 7960, 7941, 7961, 7970, and 7971 IP Phones support Cisco Voice Transmission 
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.)  

● 

No Cisco IP Phones, including 7985, support Cisco Voice Transmission Quality  

● 

Sampling rate is every 8 seconds 

● 

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. 

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.

This section describes how to prepare your server for Service Monitor installation 

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). 

● 

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).
