SIP trace

The SIPd offers runtime trace and debug logging via the Linux Console. This is intended for debug and on-site trouble shooting.

The trace-interface is found as an internal unix-socket in AMC: “/tmp/sipd_trace”. Log in via telnet (user: alpha; password: com), and type:

tst -s /tmp/sipd_trace

A few simple input commands are implemented, type single letters;

 0,1,2,3,4,5,6,7: Set tracelevel.
       0: Fatal errors only
       4: SIP/AlphaNet message trace (default)
       7: All internal debug trace also
  l:  list active calls
  h:  This text
