Cisco ASA 5500 Series Configuration Guide using the CLI

Chapter 48 Configuring the Cisco Phone Proxy

Troubleshooting the Phone Proxy

Step 2

From the ASA, verify that the CTL file for the phone proxy contains one record entry for each entity in
the network—Primary Cisco UCM, Secondary Cisco UCM, TFTP server—by entering the following
command:

hostname# show running-config all ctl-file [ctl_name]

Each of these record entries creates one entry on the IP phone trustlist. The phone proxy creates one entry
internally with the function CUCM+TFTP.

Step 3

In the CTL file, verify that each IP address is the global or mapped IP address of the entity. If the IP
phones are on multiple interfaces, additional addressing requirements apply. See

Prerequisites for IP

Phones on Multiple Interfaces, page 48-9

Configuration File Parsing Error

Problem

When the ASA receives the configuration file from the Cisco UCM and tries to parse it, the

following error appears in the debug output (debug phone-proxy tftp errors):

PP: 192.168.10.5/49357 requesting SEP00010002003.cnf.xml.sgn

PP: opened 0x193166

.......

PP: Beginning of element tag is missing, got !

PP: error parsing config file

PP: Error modifying config file, dropping packet

Solution

Perform the following actions to troubleshoot this problem:

Step 1

Enter the following URL in a web browser to obtain the IP phone configuration file from the Cisco
Unified CM Administration console:

http://<cucm_ip>:6970/<config_file_name>

For example, if the Cisco UCM IP address is 128.106.254.2 and the IP phone configuration file name is
SEP000100020003.cnf.xml, enter:

http://128.106.254.2:6970/SEP000100020003.cnf.xml

Step 2

Save this file, open a case with TAC and send them this file and the output from running the debug
phone-proxy tftp
command on the ASA.

Configuration File Parsing Error: Unable to Get DNS Response

Problem

When the ASA receives the configuration file from the Cisco UCM and tries to parse it, the

following error appears in the debug output (debug phone-proxy tftp errors):

PP: 192.168.10.5/49357 requesting SEP00010002003.cnf.xml.sgn

PP: opened 0x193166

.......

PP: Callback required for parsing config file

PP: Unable to get dns response for id 7

PP: Callback, error modifying config file

The error indicates that the Cisco UCM is configured as an FQDN and the phone proxy is trying to do a
DNS lookup but failed to get a response.
