Task flow for Configuring the TLS Proxy for Encrypted Voice Inspection
To configure the security appliance for TLS proxy, perform the following steps:
Step 1
(Optional) Set the maximum number of TLS proxy sessions to be supported by the security appliance
using the following command, for example:
hostname(config)#
tls-proxy maximum-sessions 1200
Note
The
tls-proxy maximum-sessions
command controls the memory size reserved for
cryptographic applications such as TLS proxy. Crypto memory is reserved at the time of system
boot. You may need to reboot the security appliance for the configuration to take effect if the
configured maximum sessions number is greater than the currently reserved.
Step 2
Create trustpoints and generate certificates for the TLS Proxy for Encrypted Voice Inspection. See
Creating Trustpoints and Generating Certificates, page 1-9
Step 3
Create the internal CA to sign the LDC for Cisco IP Phones. See
Creating an Internal CA, page 1-10
Step 4
Create the CTL provider instance. See
Creating a CTL Provider Instance, page 1-11
.
Step 5
Create the TLS proxy instance. See
Creating the TLS Proxy Instance, page 1-12
Step 6
Enable the TLS proxy y with SIP and Skinny inspection. See
Enabling the TLS Proxy Instance for
Skinny or SIP Inspection, page 1-13
.
Step 7
Export the local CA certificate (ldc_server) and install it as a trusted certificate on the Cisco UCM server.
a.
Use the following command to export the certificate if a trust-point with
proxy-ldc-issuer
is used
as the signer of the dynamic certificates, for example:
hostname(config)#
crypto ca export ldc_server identity-certificate
b.
For the embedded local CA server LOCAL-CA-SERVER, use the following command to export its
certificate, for example:
hostname(config)#
show crypto ca server certificate
Save the output to a file and import the certificate on the Cisco UCM. For more information, see the
Cisco Unified CallManager document:
After this step, you may use the Display Certificates function on the Cisco Unified CallManager GUI to
verify the installed certificate:
