issues.
Interoperability testing validates that the device interfaces properly with BroadWorks via
the SIP interface. Qualitative aspects of the device or device capabilities not affecting the
SIP interface such as display features, performance, and audio qualities are not covered
by interoperability testing. Requests for information and/or issues regarding these aspects
should be directed to Yealink.

Compatible Versions in the following table identify specific T4x IP Phone versions, which
the partner has identified as compatible and they should interface properly with
BroadWorks. Generally, maintenance releases of the validated version are considered
compatible and are not specifically listed here. For any questions concerning
maintenance and compatible releases, contact Yealink.
NOTE: Interoperability testing is usually performed with the latest generally available (GA)
device firmware/software and the latest GA BroadWorks release and service pack at the time the
testing occurs. If there is a need to use a non-verified mix of BroadWorks and device software
versions, customers can mitigate their risk by self-testing the combination themselves using the
BroadWorks SIP Phone Interoperability Test Plan [5].
2.2 Interface Capabilities Supported
This section identifies interface capabilities that have been verified through testing as
supported by Yealink T4x IP Phone.

NT Test item was not tested
Caveats and clarifications are identified in the Comments column.
2.2.1 SIP Interface Capabilities
The Yealink T4x IP Phone has completed interoperability testing with BroadWorks using
the BroadWorks SIP Phone Interoperability Test Plan [5]. The results are summarized in
the following table.
The BroadWorks test plan is composed of packages, each covering distinct
interoperability areas, such as “Basic” call scenarios and “Redundancy” scenarios. Each

3 BroadWorks Configuration
This section identifies the required BroadWorks device profile type for the Yealink T4x IP
Phone as well as any other unique BroadWorks configuration required for interoperability
with the T4x IP Phone.
3.1 BroadWorks Device Profile Type Configuration
This section identifies the device profile type to use when deploying the Yealink T4x IP
Phone with BroadWorks.
Create a device profile type for the Yealink T48G IP Phone as shown in the following
example. A separate device profile type should be created for each Yealink T4x IP Phone
model. The settings shown are recommended for use when deploying the Yealink T4x IP
Phone with BroadWorks. For an explanation of the profile parameters, see the
BroadWorks Device Management Configuration Guide [2].
The following device profile type shown provides the Number of Ports (number of SIP
lines) setting for Yealink T4x IP Phone. For other Yealink T4x IP Phone models, create a
new device profile type and set the Number of Ports to match the available number of SIP
lines per model according to the following table.
Model Number of Lines
T40P 3 SIP accounts, 3 line keys
T40G 3 SIP accounts, 3 line keys
T41P 6 SIP accounts, 15 line keys
T41S 6 SIP accounts, 15 line keys
T42G 12 SIP accounts, 15 line keys
T42S 12 SIP accounts, 15 line keys
T46G 16 SIP accounts, 27 line keys
T46S 16 SIP accounts, 27 line keys
T48G 16 SIP accounts, 29 line keys
T48S 16 SIP accounts, 29 line keys
T49G 16 SIP accounts, 29 line keys

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.
