OK, I didn't realize that. Will try it later then.

It doesn't necessarily mean that it's the same on my Xen host. As far
as I follow it's a per-kernel-compilation setting.

What do you call "unmanaged"? It's a Virtuozo-style host, so the
kernel is dictated by the hosting env.

The VPSLink service I have is Xen so although they control the kernel
I can pick one of few and probably switch to a new one.

OK, I missed that.

Thanks for the pointer. It looks like the relevant sentence was cut in
the middle:

"With Asterisk 1.4, once Asterisk 1.4.N is released, Asterisk 1.4.X is
no longer supported, where X
