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].

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
package is composed of one or more test items, which in turn are composed of one or
more test cases. The test plan exercises the SIP interface between the device and
BroadWorks with the intent to ensure interoperability sufficient to support the BroadWorks
feature set.
