Cisco ASA Series Firewall CLI Configuration Guide
 
Chapter 15      Using the Cisco Unified Communication Wizard
  Configuring the Phone Proxy by using the Unified Communication Wizard
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).
If your network includes Cisco IP Communicators (CIPC) or you have LSC enabled IP phones, you must 
import the CAPF certificate from the Cisco UCM. The certificate will be used to generate the LSC on 
the IP phones.
If the Cisco UCM has more than one CAPF certificate, you must import all of them to the ASA. However, 
the wizard supports configuring only one CAPF certificate, which is the default. To import more than 
one CAPF certificate, go to Configuration > Device Management > Certificate Management > Identity 
Certificates.
You can configure LSC provisioning for additional end-user authentication. See the Cisco Unified 
Communications Manager configuration guide for information. 
Step 1
Check the Enable Certificate Authority Proxy Function check box. The remaining fields in the page 
become available. 
Step 2
Enter the private IP address of the LSC provider. 
Step 3
In the Public Address field, specify whether to use the IP address of the ASA public interface or enter 
an IP address. 
Specifying the private and public IP addresses for the LSC provider, creates an access list entry that 
allows the IP phones to contact the Cisco UCM by opening the CAPF port for LSC provisioning. 
Step 4
In the Translation Type field, select the Address only or Address and ports radio button. 
The IP phones must contact the CAPF service on the Cisco UCM. The address translation type (Address 
only versus Address and ports) you select for CAPF must match the address translation type of the Cisco 
UCM on which the CAPF service is running. You set the address translation type for that Cisco UCM 
server in the previous step of this wizard (see 
),
By default, the CAPF Service uses port 3804. Modify this default value only when it is modified on the 
Cisco UCM.
Step 5
If you selected the Address and ports radio button, enter the private and public ports for the CAPF 
service. 
Step 6
Click the Install CAPF Certificate button. The Install Certificate dialog box appears. See 
Step 7
Click Next.
Configuring the Public IP Phone Network
The values that you specify in this page generate the address translation rules used for the IP phones and 
configure how the ASA handles IP phone settings. 
Step 1
From the Interface drop-down list, choose the interface on which the ASA listens for connections from 
IP phones.
Step 2
To preserve Call Manager configuration on the IP phones, check the Preserve the Unified CM’s 
configuration on the phone’s service check box. When this check box is uncheck, the following service 
settings are disabled on the IP phones:
