If you could pick any firewall to put in front of an Asterisk server, which one would you choose and why?
I’m planing on 75 IP phones on a MPLS network. My thoughts are to put the Asterisk server and the 75 IP phones behind a firewall. Access to the PSTN would be through a Digium PRI card. The only communication on the Asterisk server going in and out of the firewall would be to support about 10 remote workers. The firewall will be the main “corporate” firewall for the company.
All suggestions, thoughts and ideas are welcome! Thanx!
