Chapter 2 Required Configuration Tasks
How to Configure Cisco IOS Telephony Service
DETAILED STEPS
Enabling Files on the TFTP Server
When the Cisco IP phone contacts the TFTP server, it requests a configuration (SEPDEFAULT.cnf) file.
The SEPDEFAULT.cnf file contains the IP address of the Cisco IOS Telephony Service router.
Tip Make sure that the router’s Flash memory contains the SEPDEFAULT.cnf file, the XMLDefault.cnf.xml
file, and the appropriate phone firmware before enabling access to the phone firmware.
SUMMARY STEPS
1. tftp-server flash:SEPDEFAULT.cnf
2. tftp-server flash:XMLDefault.cnf.xml
3. tftp-server flash:firmware
Command Purpose
Step 1
Router(config)# telephony-service
Enters telephony-service configuration mode.
Step 2
Router(config-telephony-service)# ip
source-address ip-address [port port] [any-match |
strict-match]
Identifies the IP address and port number the
Cisco IOS Telephony Service router uses for the IP
phone service. The default port is 2000.
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. These files are specific to
the router and cannot be shared by multiple routers.
Use the any-match keyword to instruct the router to
permit Cisco IP phone registration, and use the
strict-match keyword to instruct the router to reject
Cisco IP phone registration attempts if the IP server
address used by the phone does not exactly match the
source address.
Tip Make sure that the SEPDEFAULT.cnf file and
the XMLDefault.cnf.xml files are registered to
the TFTP server. See the “Enabling Files on the
TFTP Server” section on page 2-10.
