Configuring PSTN Cause Code Mapping
This section describes the method of mapping between SIP status code and
PSTN Cause code. For calls to be established between a SIP network and a
PSTN network, the two networks must be able to interoperate. One aspect of
their interoperation is the mapping of PSTN cause codes, which indicate
reasons for PSTN call failure or completion, to SIP status codes or events.
The opposite is also true: SIP status codes or events are mapped to PSTN
cause codes.
A Ubigate iBG2016 provides a SIP- PSTN default mapping table. The method for
an operator to change the mapping is also provided. You can change the mapping
using set pstn-cause command and set sip-status command. You can check the
current mapping table settings using the show sip-ua maps command.
Restrictions for PSTN Cause Code Mapping
Using the command described above, you can change the existing inter-code
mapping, not create a new code.
