[asterisk-users] asterisk SIP domain (in LAN or DMZ)?

[Joao Pereira]

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

Thanks
Regards
