Depends on what level of firewall you're looking for.

For a full firewall on either a dedicated system or one of your own, I
cannot strongly enough recommend Astaro Linux firewall. Better
throughput than a pix, worlds easier to operate and configure, and
comparable in price. Very SIP/VoIP friendly. Loads of optional modules
(we use its mail filter module to filter spam/viruses for several
hundred thousand user mailboxes, for instance) to limit the cost to what
you need.

Also has a built in SIP Proxy, although I've never used it.

Excellent platform.


Of course, at home, I just use a little Linksys WRT box. It's hardly a
corporate-grade firewall, but it's quite SIP-friendly.
