Double NAT ?! Boy, you are really asking for trouble. It's either tunneling or FWD then. Sign up for two free accounts with FWD at http://www.freeworlddialup.com, one for your Asterisk server, one for your Grandstream phone. Then on both the Asterisk server and the phone, register with the FWD server. Put reinvite=no and canreinvite=no into your sip.conf for FWD (or use IAX to connect to FWD). Finally set up your dialplan so that you call the phone's FWD number if you dial the extension you want to give the phone, like so ... exten => 2001,3,Dial(SIP/[EMAIL PROTECTED],60,r) ... assuming that your Grandstream phone's FWD number was 12345 On your Asterisk server, the phone would then be known as 2001 but it would be dialled as 12345 on FWD. You could then send incoming calls from FWD with the caller ID of your GS phone to a context where it gets an IVR menu that allows it to dial other extensions on your Asterisk server. keywords for this are GotoIf, Background and DISA. rgds benjk -- Sunrise Telephone Systems, 9F Shibuya Daikyo Bldg., 1-13-5 Shibuya, Tokyo, Japan.
