Chris, I don't know if the ISP is messing with your SIP packets but I can share my experiences with Alcatel SpeedTouch 510v4 ADSL modems & SIP and they are not positive with firmware 4.2.7 and older. There is a new firmware version (4.3.1) that has less braindead NAPT abilities. So far I can register my Asterisk box with sipgate.de & sipgate.co.uk fine. Perhaps you could try to upgrade the firmware of the modem. An interesting new feature is that 4.3.1 allows you to assign the public IP address of your connection to a LAN device after going through the NAPT rules you have entered. Pasted from the modem's config webpage: This page allows you to assign the public IP address of your Internet Connection(s) to a specific device on your local network... You might want to do this if: * You encounter issues with some applications through the Network Address Translation engine of your SpeedTouch. * This device is running server applications (web server, ...) and you want it to be accessible from the internet. * This device has to be considered as the unique entry to your local network (DMZ). Try with ordinary NAPT rules first and if that doesn't work perhaps try to assign the ADSL IP address to the phone (I don't know about the security implications though). Good luck!
