Well router and firewall are very different...it depends on what you are trying to accomplish.
If you are trying to secure an Asterisk-based call center, get a real security product. Look here for details: http://www.voip-info.org/wiki/view/Asterisk+security This covers firewall, Asterisk lock-down, and Asterisk specific security. The average break-in/fraud cost is $25,000 per day. (watch the Astricon videos for more details). So going cheap on security isn't a smart move for a commercial installation. If you just want a router/switch, figure out the simultaneous call capacity x codec demands in bps, and there is your backplane switching speed requirements. Even with 100 simultaneous calls at g711, a lower end Cisco (3xx) router/switch will have no problem. -M- -----Original Message----- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Ernie Dunbar Sent: Friday, November 20, 2015 3:25 PM To: Asterisk Users Subject: [asterisk-users] Which router/firewall would you use for a virtual-PBX Asterisk installation? Hi everyone. We've got a fairly large base of customers who use our Asterisk server for phone service in a virtual PBX kind of way, where the server is security hardened and exposed to the internet for them to connect to remotely with SIP and IAX. It's certainly not the sort of affair where we're running it as a PBX just within the building. As a result, we see network traffic coming through eth0 between 512 Kbps and about 3.0 Mbps, depending on the time of day. We haven't so far been using a hardware firewall/router on our server network, but it's becoming increasingly clear that we need to. We have enough experience to know that Asterisk is pretty sensitive when it comes to network hardware in our situation - we've had to replace one otherwise perfectly good 100 Mbps network switch because it simply wasn't able to keep up with the amount of streaming audio we put through it, and it badly affected voice quality. We have other traffic flowing through our server network too, including a significant amount of e-mail and web traffic, although that's not quite as sensitive to the quality of our network hardware. If you've got these large requirements for Asterisk, I'd love to hear what you use for a router, and whether that router has met your needs. It would also be nice to hear about what kinds of routers to avoid that you may have tried in the past and found lacking. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
