<br>Hi,<br><br>I am relatively new to Asterisk and am looking for help in configuring an IP based phone. This phone is not on the same subnet as the PBX. I read that there could be an issue with NAT so I am bypassing this by connecting temporarily with an Internet IP. So far, I have configured the server extension with the phone MAC address along with configuring the phone unit with IP, Gateway and SIP info. Upon rebooting the phone, I am getting 'NO Service' message. Kind of surprised there is no IP option on the PBX Manager for this extension. Any help would be much appreciated. Thanks.<br>
