"What is CentOS?
CentOS is an Enterprise Linux distribution based on the freely available
<ftp://ftp.redhat.com/pub/redhat/linux/enterprise/> sources from Red Hat
Enterprise Linux. Each CentOS version is supported for 7 years (by means of
security updates). A new CentOS version is released every 2 years and each
CentOS version is regularly updated (every 6 months) to support newer
hardware. This results in a secure, low-maintenance, reliable, predictable
and reproducible Linux environment."
CentOS 4 ( http://wiki.centos.org/FAQ/CentOS4 ):
"We intend to support CentOS-4 updates until Feb 29, 2012"
CentOS 5 ( http://wiki.centos.org/FAQ/CentOS5 ):
"We intend to support CentOS 5 until Mar 31st, 2014"
So if you don't want major upgrades for a while you might want to go with
the latest version. To put it into Microsoft terms... the minor version is
like a service pack. So CentOS 4.7 is really a base lined version 4,
service pack 7. You get the new features in major releases (like there are
no more "smp" kernels in 5 to deal with)

Tzafrir thanks for the comments. I am not done playing with this and in the
end I may well use newer software as you suggest.
According to wikipedia CentOS 4.7 was released OCT. 2008 (7 months ago) is
that really consider that old? I am looking to setup a phone system that I
would hope would not require any major software upgrades for many years.

I’d
probably go with 1.4.21.X since anything above that replaces zaptel with

There are still a lot of things “To be worked out” in DAHDI
