Chapter 16 Using the Cisco Unified Communication Wizard

Configuring the Phone Proxy by using the Unified Communication Wizard

statements, you must delete them manually by using the appropriate area of ASDM or rerun the Unified Communications wizard without making any changes and apply the configuration to to remove these statements.

The servers that the IP phones must trust can be deployed on the network in one of the following ways:

•All the services required by the Cisco UCM server, namely the Cisco UCM, TFTP, and CAPF services, are running on one server. In this deployment, only one instance of each service exists. For this deployment, you can select Unified CM+ TFTP as the server type. You can either use Address only or Address and ports for address translation. Cisco recommends that you specify Address and ports for increased security.

•Deployments for larger enterprises might have redundant Cisco UCMs and dedicated servers for TFTP and CAPF services. In that type of deployment, use Address only for voice address translation and Address only or Address and ports for TFTP.

Table 16-1lists the ports that are configured for Address and port translation by default:

Step 1 In the Server Type field, select the server from the drop-down list: Unified CM, TFTP, or Unified CM + TFTP. Select Unified CM + TFTP when the Cisco UCM and TFTP server reside on the same device.

Note Depending on which type of server you select (Unified CM or TFTP), only the necessary fields in this dialog box become available. Specifically, if the server type is Unified CM, the TFTP section in the dialog is unavailable. If the server type is TFTP, the Voice section is unavailable.

Step 2 In the Private Address field, specify the actual internal IP address of the server.

Step 3 In the FQDN field, enter the fully-qualified domain name of the server, which includes the hostname and domain name; for example, ucm.cisco.com (where ucm is the hostname and cisco.com is the domain name).

If you are configuring a Unified CM server, enter the fully-qualified domain name configured on the Cisco UCM.

If you are configuring a TFTP server, only specify the TFTP server fully-qualified domain name when that server is configured with FQDN. If the TFTP server is not configured with FQDN, you can leave the field blank.

Note Entering the fully-qualified domain name allows the ASA to perform hostname resolution when DNS lookup is not configured on the ASA or the configured DNS servers are unavailable.See the command reference for information about the dns domain-lookupcommand.

Step 4 In the Address Translation section, select whether to use the interface IP address or to enter a different IP address.
