Figure 675 PSTN release cause code mapping configuration page
You can enter the SIP status code into the corresponding SIP Status Code (400-699) field. Because
the PSTN release cause code 16 corresponds to a SIP request message, instead of a SIP status
code, you can configure no SIP status code for 16.
Click Load Default Value to restore the default mappings between PSTN release cause codes and
SIP status codes.
Configuring SIP status code mappings
Select Voice Management > Call Connection > SIP Connection from the navigation tree, and
click the SIP Status Code Mapping tab to access the page as shown in Figure 676.
