the packets do not flow through the proxy and the proxy is not able to
determine the length of the call.
Please remember that the call log is sensitive information and
should not be accessible to unauthorized persons. See the comments on
security in this manual.

Pending Calls

Similar to the finished calls the proxy keeps a list about the not-
finished calls. Because in SIP, a failure code like 401 does not mean the
end of this call, the proxy does not differentiate between ongoing calls
and failed calls. Therefore, all non-finished calls are kept in the list of
"pending calls".
The web server displays the pending calls in the same fashion as
the finished calls. If you want to see the packet history associated with
the calls, just click on the link shown in the web interface.

Call Log File Format

A line in the call log file has the following format:
[Start time]: [Seconds] [Duration] [From] [To]
The start time is separated by a colon from the rest, so that it is
easier to parse the log file automatically. The date itself has the format
Weekday Month Date Time Year, with the time in the format hour:minutes:
seconds. An example would be "Fri Jul 5 16:17:06 2002".
The duration of the call is given in seconds.
The from and to addresses are taken from the From: and To: URL
in the headers of the INVITE packet. If the hostname in the URL match
the hostname the proxy is responsible for, they are stripped from the URL.
This makes the log easier to read.
The proxy supports also RADIUS and a snom-proprietary
XML format to record calls. Please see the FAQ on this topic for more
information.
