You should go into deep knowleadge, it's a MUST to work with a sip proxy. You
could begin reading the "Getting starting gide" and so.

Yes, you could use it into a VM, no timming issues like Asterisk. Talking
about backup and so ... you only need to do a backup of the .cfg file and the
database backend you use, so you will not get any real advantage of running
inside a VM from backup point of view.

It depends on lot of variables, like available mem, CPU power, network (the
most important part), but also how complex is your .cfg about request
proccessing, how do you handle database request, etc.
So there is not a magic formula, but there are sip-proxies around the world
working with Million of users.

That's a setup, not direcly related with the software you use.

There are not "simple" scenarios in SIP world and faiolver is very-complex
one.

That's because Opensips it's a proxy, not a PBX, not a B2BUA, etc., it doesn't
manage media, so you need some "complements" to have a "full-featured VoIP
system"
