Summary:                    High CPU usage, choppy sound
Description: 
After upgrading from Asterisk 1.6.1.6 to 1.6.1.8 I seem to have a random
problem with high CPU usage.  When making a SIP to SIP call or SIP to
System call Asterisk process CPU usage goes much higher than normal and the
sound get's choppy.  This is somewhat random but occurs fairly regularly,
maybe 50% of the time.

If it happens it happens as soon as a call is answered.  CPU usage
sometimes stays high for minutes and will suddenly go low even though I
didn't do anything.  More often than not it only stays high for a short
period of time and then goes back to normal.

I am running 64bit CentOS 5.4.  Log files and Asterisk CLI -vvvvvvvvvvr
look clean.  

Not sure if this is useful but I will attached a gdb.txt file taken while
it is happening

---------------------------------------------------------------------- 
I have installed 1.6.2.0 RC3 and now RC4 and so far it looks like maybe the
issues is not there anymore.  Still testing.  I have also added some
development packages.  It maybe have had something to do with a missing
dependency but I have not information either way to confirm or deny that.

Would it be too much to ask for an exact list of all the dependencies and
packages required.  I know that I can just install everything or
Development tools group but that adds hundreds of megs of stuff I don't
want or need.  On hardware limited or VPS systems that is not practical.

It sure would be nice if there was an up to date list of dependencies
required so I can only install the packages needed and don't have to
constantly guess or overinstall to be sure.
