T4x IP Phone Configuration

The T4x IP Phone can be configured with a configuration file using the Trivial File Transfer
Protocol (TFTP) or through its embedded web server. The following examples describe
how to set the parameters using a configuration file. This configuration description
assumes the T4x IP Phone uses the Dynamic Host Configuration Protocol (DHCP) to get
an IP address, TFTP server, and other network settings. The T4x IP Phone should be
configured to load the configuration file each time it resets or re-synchronizes. For
detailed information on automated provisioning, see the Yealink T4x IP Phone User Guide
[1].
The capabilities of the T4xG IP Phone have been verified for use with BroadWorks based
on the settings described in the following table. For more information on the meaning,
purpose, and applicability of the individual configuration items see the Yealink T4xG IP
Phone User Guide

Description
"y0000000000xx.cfg", where "xx"
is associated with the hardware
version of Yealink device.
Purpose
Set the T4xG IP Phone SIP server to
the Fully Qualified Domain Name
(FQDN) for the BroadWorks
Application Server cluster.
The domain must match the domain
configured for the BroadWorks
subscriber's line/port domain.
Set the Outbound Proxy to the
session border controller (SBC) if one
is deployed between the T4xG IP
Phone and BroadWorks.
If there are redundant SBCs, set it to
the FQDN for the SBC cluster.
The SIP timers should be set to levels
short enough to support a timely
failover when there is no server
response.
Set the registration period.
