Are there known bugs in the Perl module?

The Perl module does have a few shortcomings that may be regarded as bugs.

- Missing module functions. Not all functions of other modules are available for Perl access. The reason for this is a design property of &kamailio;. Making available more functions is work in progress.

- Perl and threads. Perl itself is, when compiled with the correct parameters, thread safe; unfortunately, not all Perl modules are. The DBI modules, especially (but not restricted to) DBI::ODBC are known NOT to be thread safe.

  Using DBI::ODBC -- and possibly other non-thread-safe Perl extensions -- may result in erroneous behavior of &kamailio;, including (but not restricted to) server crashes and wrong routing.

Where can I find more about &kamailio;?

Take a look at &kamailiohomelink;.

Where can I post a question about this module?

First at all check if your question was already answered on one of our mailing lists:

- User Mailing List - &kamailiouserslink;

- Developer Mailing List - &kamailiodevlink;

E-mails regarding any stable &kamailio; release should be sent to &kamailiousersmail; and e-mails regarding development versions should be sent to &kamailiodevmail;.
