Proponents of proprietary solutions always like to say "If an Open Source
solution breaks, who can you call?" The answer is, "Any sufficiently-competent
programmer -- it may be broken, but we have all the pieces". Whereas if you
spend money on proprietary software and it breaks, then there is only *one*
place you can call -- and you'd better hope they are interested to fix your
On the other hand, if you could get full Source Code and Modification Rights
(basically, "everything we could do with a GPL program except distribute
copies"), a proprietary solution might not be so bad after all. But since
the goal of most proprietary software vendors is to extract money from you and
maintaining you in a state of perpetual helplessness is highly desirable in
the course of this, do not expect to get such a deal in real life.

Not sure about this. We're still using the original chan_sip driver.

It's about as easy as compiling anything from Source Code. Harder than LAME
MP3 encoder, but easier than the Linux kernel. If you altered `monop` from
the BSDgames package to make the streets match your local edition of the game,
you will have no problem whatsoever with building Asterisk.
If you understand the process of what you are doing -- basically, setting up
an automated process that will examine your server hardware and software
configuration (configure), choosing which parts of Asterisk you want to
include (make menuselect), compiling the selected human-readable Source Code
into binary code that the computer can understand natively (make) and then
moving the compiled binary code and configuration files from the Source Code
folder to where the computer is expecting for them to be (make install) then
you should not have too many problems.
It is always preferrable to compile your own Asterisk to fit your hardware and
include just the bits you want, rather than rely on anyone else's pre-compiled

The latest one.

You can certainly use Windows softphones to talk to Asterisk, but Asterisk
itself requires a non-toy underlying operating system. Ubuntu and CentOS are
the best-supported Linux distributions. Asterisk has also been seen working,
to greater or lesser extents, on Solaris and the BSDs. But Linux was the
original development environment (although one of the two original projects
that ended up merging and becoming Asterisk, many years ago, was originally
developed on FreeBSD), and is what most Asterisk telephonistas know.
Any hardware which is capable of running Windows can, of course, run Linux;
and usually better.
