</div></div>Depends on what level of firewall you're looking for.<br>
<br>
For a full firewall on either a dedicated system or one of your own, I<br>
cannot strongly enough recommend Astaro Linux firewall. Better<br>
throughput than a pix, worlds easier to operate and configure, and<br>
comparable in price. Very SIP/VoIP friendly. Loads of optional modules<br>
(we use its mail filter module to filter spam/viruses for several<br>
hundred thousand user mailboxes, for instance) to limit the cost to what<br>
you need.<br>
<br>
Also has a built in SIP Proxy, although I've never used it.<br>
<br>
Excellent platform.<br>
<br>
<br>
Of course, at home, I just use a little Linksys WRT box. It's hardly a<br>
corporate-grade firewall, but it's quite SIP-friendly.<br>
