Licensing
The Cisco UC 540 includes 24 user licenses. These licenses enable the use of Cisco Unified IP Phones and allow
users to access the IP PBX features, including voicemail. In addition, supplementary user licenses are bundled to
help with deployments that need a few extra licenses. For additional licensing needs, the L-UC-PRO-8U= may be
ordered. This increases the existing license count by eight. Table 5 lists the number of users supported based on
the hardware/license configurations. The UC 540 also has built-in licenses for unified communications features.
Table 4 lists the license count bundled within the system for each feature. Guidance for licenses associated with
voice messaging on the UC 540 is included in Table 6.
Note: Among the 24 base licenses provided 16 of them are provided as supplemental licenses.
