Information About the Cisco Phone Proxy

Note

As an alternative to authenticating remote IP phones through the TLS handshake, you can configure
authentication via LSC provisioning. With LSC provisioning you create a password for each remote IP
phone user and each user enters the password on the remote IP phones to retrieve the LSC.

Because using LSC provisioning to authenticate remote IP phones requires the IP phones first register
in nonsecure mode, Cisco recommends LSC provisioning be done inside the corporate network before
giving the IP phones to end-users. Otherwise, having the IP phones register in nonsecure mode requires
the Administrator to open the nonsecure signaling port for SIP and SCCP on the ASA.

See “

Example 5: LSC Provisioning in Mixed-mode Cisco UCM cluster; Cisco UCM and TFTP Server

on Publisher, page 48-49

“. See also the Cisco Unified Communications Manager Security Guide for

information on Using the Certificate Authority Proxy Function (CAPF) to install a locally significant
certificate (LSC).
