Cisco IOS Telephony Service, Version 2.02

Chapter 5 Command Reference

ip source-address (telephony-service)

The ip source-address command enables the router to receive messages from the Cisco IP phones

through the specified IP address and port.

The ip source-address command helps the router to autogenerate the SEPDEFAULT.cnf file and the

XMLDefault.cnf.xml file, which are stored in the router’s Flash memory. The SEPDEFAULT.cnf file

contains the IP address of one of the Ethernet ports of the router to which the phone should register; the

XMLDefault.cnf.xml file contains the IP address of one of the Ethernet ports of the router to which the

ATA adapter should register.

Note The SEPDEFAULT.cnf file and the XMLDefault.cnf.xml file are specific to the router and cannot be

shared by multiple routers.

At some point, you must use the following commands to enable access to the SEPDEFAULT.cnf file and

XMLDefault.cnf.xml file:

Router# tftp-server flash:SEPDEFAULT.cnf

Router# tftp-server flash:XMLDefault.cnf.xml

The Flash file system on some routers limits the number of times the Flash file can be written to or

modified. After this limit is exceeded, the Flash memory must be manually erased and the files contained

in the Flash file must be reloaded.

The ip source-address command can write or modify the SEPDEFAULT.cnf file or the

XMLDefault.cnf.xml file only when parameters are actually changed. The file is not deleted by

executing the no ip source-address command. However, the SEPDEFAULT.cnf file or the

XMLDefault.cnf.xml file can be manually removed using the delete command.

If the ip source-address command is executed with changed parameters after the Flash file write limit

is exceeded, the command fails. To see the detailed operation of the ip source-address command, turn

on the debug ephone detail command.

Examples The following example shows how to set the IP source address and port:

Router(config)# telephony-service

Router(config-telephony-service)# ip source-address 1.6.21.4 port 2000 strict-match
