2.3  Known Issues 
This section lists the known interoperability issues between BroadWorks and specific 
partner release(s). Issues identified during interoperability testing and known issues 
identified in the field are listed. 
The following table provides a description of each issue and, where possible, identifies a 
workaround. The verified partner device versions are listed with an “X” indicating that the 
issue occurs in the specific release. The issues identified are device deficiencies or bugs, 
so typically not BroadWorks release dependent. 
The Issue Number is a BroadSoft ExtraView partner issue number if the testing was 
performed by BroadSoft. If the testing was performed by the partner or a third party, the 
partner may or may not supply a tracking number. 
For more information on any issues related to the particular partner device release, see 
the partner release notes.
