The CPU MHz is 2200.

This is why I go for unmanaged. The box from which I'm writing this got upgraded from Etch to Lenny.

That is: a release candidate for the branch 1.6.1 . A while before that 1.6.0.5 was released, which is the fifth maintinance release of branch 1.6.0 . > about three days ago when I looked .

The closest thing I found for describing it is: http://www.asterisk.org/node/48539 At the moment 1.4 is still supported, but I'm not sure I'd use it for new installations. -- Tzafrir Cohen | tzaf...@jabber.org | VIM is http://tzafrir.org.il | | a Mutt's tzaf...@cohens.org.il | | best ICQ# 16849754 | | friend _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
