Secure Cisco Unified IP phones supported in secure SCCP and SIP SRST must have certificates
installed and encryption enabled.
The SRST router must have a certificate; a certificate can be generated by a third party or by the
Cisco IOS certificate authority (CA). The Cisco IOS CA can run on the same gateway as Cisco
Unified SRST.
Certificate trust lists (CTLs) on Cisco Unified Communications Manager must be enabled. For
complete instructions, see the "Configuring Secure IP Telephony Calls" procedure in the
