i´ve tried to configure security on a 2821 Router but some commands are unrecognized by the IOS .I´ve created the CA, the necessary Trustpoints and authentificated them but i cannot configure the telephony-service parameters because the commands device-security-mode, server-security-mode, tftp-server-credentials and secure-signaling are all unrecognized. Same goes for the ctl-client and capf-server. The IOS Version is 12.4(15)T9. If anyone have a solution i´ll be thankfull.
