Enabling Logging and Debugging
The PHONE ADAPTER uses the following parameters to enable logging and debugging (both using
the syslog protocol over UDP.)
Syslog_Server
Debug_Server
Debug_Level

Error and Log Reporting
The PHONE ADAPTER Error Status Code (ESC) is used to indicate the current operation status of
the PHONE ADAPTER unit. An error state can be a relatively long transient state or a steady state.
The state is also represented by a special blinking pattern of the Status LED (next to the RJ-11 ports).
The Error Status Code is a 4 digit number. The first digit indicates the error class: 1xxx represents
normal operation states while 2xxx – 9xxx represent error states that must be fixed for the unit to
function properly. The status code values can be read from the IVR option XXX or from the PHONE
ADAPTER web-page.

Internal Error Codes
The PHONE ADAPTER defines a number of internal error codes (X00–X99) to facilitate configuration
in providing finer control over the behavior of the unit under certain error conditions. They can be
viewed as extensions to the SIP response codes 100–699. The definitions are shown below
