Mapping PSTN Release Cause to SIP Response

The MediaPack FXO is used to interoperate between the SIP network and the PSTN/PBX.
This interoperability includes the mapping of PSTN/PBX Call Progress Tones to SIP 4xx or
5xx responses for IP Tel calls. The converse is also true: For Tel IP calls, the SIP 4xx or
5xx responses are mapped to tones played to the PSTN/PBX.
When establishing an IP Tel call, the following rules are applied:
If the remote party (PSTN/PBX) is busy and the FXO gateway detects a Busy tone, it
sends 486 Busy to IP. If it detects a Reorder tone, it sends 404 Not Found (no route to
destination) to IP. In both cases the call is released. Note that if
DisconnectOnBusyTone is set to 0, the FXO gateway ignores the detection of
Busy/Reorder tones and doesn't release the call.
For all other FXS/FXO release types (caused when there are no free channels in the
specific trunk group, or when an appropriate rule for routing the call to a trunk group
doesn't exist, or if the phone number isn't found), the gateway sends a SIP response
(to IP) according to the parameter DefaultReleaseCause. This parameter defines
Q.931 release causes. Its default value is '3', which is mapped to the SIP 404
response. By changing its value to '34', the SIP 503 response is sent. Other causes
can be used as well.

Call Detail Record

The Call Detail Record (CDR) contains vital statistic information on calls made by the
gateway. CDRs are generated at the end and (optionally) at the beginning of each call
(determined by the parameter CDRReportLevel), and then sent to a Syslog server. The
destination IP address for CDR logs is determined by the parameter CDRSyslogServerIP.
For CDR in RADIUS format, refer to 'Supported RADIUS Attributes' on page 345.
The following table lists the CDR fields that are supported.
