In our lab, we're current using a Cisco 3925 ISR with IOS 15.7 using CME 12.0.
We're able to setup an environment of multiple Cisco 8841's, both through auto-register and using individual dedicated voice pools, and we're able to generate and push out a CTLFile using TFTP. However, we cannot find a way to generate signed CNF files (cnf.xml.sgn) to support a secure SIP environment.
The same router is hosting the CA and CAPF server. The CTL has been configured as well.
I'm trying to mimic the following in SIP, but I'm unsure if it's possible:
telephony-service
secure-signaling trustpoint cme-sccp
server-security-mode secure
device-security-mode authenticated
tftp-server-credentials trustpoint cme-tftp
I can post our running config if required.
