Example 5: LSC Provisioning in Mixed-mode Cisco UCM cluster; Cisco UCM
and TFTP Server on Publisher
Figure 48-6 shows an example of the configuration for a mixed-mode Cisco UCM cluster where LSC
provisioning is required using the following topology.
Note Doing LSC provisioning for remote IP phones is not recommended because it requires that the IP phones
first register and they have to register in nonsecure mode. Having the IP phones register in nonsecure
mode requires the Administrator to open the nonsecure signaling port for SIP and SCCP on the ASA. If
possible, LSC provisioning should be done inside the corporate network before giving the IP phones to
the end-users.
In this sample, you create an access list to allow the IP phones to contact the TFTP server and to allow
the IP phones to register in nonsecure mode by opening the nonsecure port for SIP and SCCP as well as
the CAPF port for LSC provisioning.
Additionally, you create the CAPF trustpoint by copying and pasting the CAPF certificate from the Cisco
UCM Certificate Management software.
