Hi, <br><br>In my opinion, you should keep your Asterisk, probably with PSTN Cards, inside your network and just setup an OpenSer or even simpler another Asterisk server on your DMZ.<br><br>This way you will enable ENUM and URIs for your Clients, and will prevent much better any DoS, intrusion or any other backhole that would let external users places PSTN calls through your server.
<br><br>At the sametime if something goes wrong on outside world, your Lan VoIP going will be kept 99,99% fully functional and let you make and receive calls through PSTN.<br><br>Good Luck,<br><br>Marco Mouta<br>Ps. Qualquer coisa apita:)

Hello<br>I want to use Asterisk to implement a SIP Domain allowing my clients to<br>do URI dialing and receive calls from the Internet through URIs and ENUM.<br>My question is, should I put my Asterisk outside the firewall (in the
<br>DMZ) to allow connections to the Internet?<br>Or should I have it inside my local network and put a SIP Proxy (like<br>Openser) in the DMZ to implement the SIP domain?<br><br>Thanks<br>Regards<br>Joao Pereira<br><br>_______________________________________________
