 For some reason our Asterisk box is doing something really unusual following 
 applying a routine update to CentOS 5 on Monday.

 We have Asterisk 1.4.2 and its been working great for years.  But now when 
 the phone system receives an incoming SIP call, its not providing any audible 
 dial sound to any caller.  It is recognizing the incoming call, and after no 
 answer for about 5 rings or so, it goes to voice mail.  But there is no 
 audible 'ring' to the caller.  Just nothing - blank, empty silence.

 Of course any automated answering system (ie. business phone menu, etc.) that 
 we have works just fine.  Its just the lines that go directly to an internal 
 phone that are no longer providing any audible ring which is sending a 
 message to the caller that their call didn't go through.

 Does anyone have any idea what might cause this?

Definitely check your firewall settings.

Definitely consider rebuilding against the libs as they now exist on
your machine. CentOS (which are really RedHat) library changes aren't
always fully disclosing the things that actually change.

The worst example in recent memory was when a CentOS update changed
the defaults to sudo, and you had to go manually override to allow
sudo to work without a tty.

Some more info on this weirdness

Seems that if I play any audio out from Asterisk first the problem goes away.  
its almost like the entire audio engine isn't being 'initialized' or something 
on those direct calls.  I found that if I execute a Swift(Please Wait) before I 
call the Dial command in my extensions, then it plays the ringing tone as 
expected.  But if I receive a call, and then try and have it transferred 
directly to a phone extension via a Dial command (which used to work perfectly 
well), the calling party never hears a ringing tone.  But if I play some audio 
purposely before, then it rings
