Using the Gratuitous ARP Feature

Cisco IP Telephony Locale Installer Installation and Configuration

For installation and configuration instructions, see the Using the Cisco IP Telephony Locale Installer
with Cisco CallManager 3.3(3) manual.
The Cisco ATA supports the Cisco IP Telephony Locale Installer, available with Cisco CallManager
release 3.3(3). Network locale files provide country-specific phone tones and gateway tones, if available.
For installation and Cisco ATA configuration instructions, see the Using the Cisco IP Telephony Locale
Installer with Cisco CallManager 3.3(3) manual.
Using the Gratuitous ARP Feature
The Cisco ATA updates an Ethernet-to-IP address mapping when it accepts an ARP response. By default,
the Cisco ATA uses the Gratuitous ARP (GARP) feature, which means that the Cisco ATA accepts an
ARP response only after it sends an ARP request. The Cisco ATA ignores ARP responses that are not
the result of prior requests.
However, you can disable GARP, which would allow the Cisco ATA to accept all ARP responses.
To go to the GARP field, first bring up the Cisco CallManager Administration Web page. Select Phone
from the Device menu to go to the Find and List Phones screen. Next, search for your Cisco ATA, then
click on its name. You are now taken to the Phone Configuration screen, which contains the the
Gratuitous ARP field in the Product Specific Configuration category.
