4 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 [1].
Configuration Files
Files Provided by Partner Level Description
y0000000000<xx>.cfg system configuration file “y0000000000xx.cfg”, where “xx”
is associated with the hardware
version of Yealink device.
<MACADDRESS>.cfg device-specific
configuration file
4.1 System Level Configuration
This section describes system-wide configuration items that are generally required for
each T4x IP Phone to work with BroadWorks. Subscriber-specific settings are described
in the next section.
Step Command Purpose
System Configuration Items y0000000000<xx>.cfg
Step 1 Set SIP Proxy/Domain.
account.1.sip_server.1.address =
as.broadworks.net
account.1.sip_server.1.port = 5060
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.
Step 2 Set Outbound Proxy.
account.1.outbound_proxy_enable =
1
account.1.outbound_proxy.1.address
= sbc.broadworks.net
account.1.outbound_proxy.1.port =
5060
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.
Step 3 Set SIP Timers.
sip.timer_t1 = 0.5
sip.timer_t2 = 4
sip.timer_t4 = 5
The SIP timers should be set to levels
short enough to support a timely
failover when there is no server
response.
Step 4 Set Register Expire Timer.
account.1.sip_server.1.expires =
3600
Set the registration period.
