Registering a Remote Phone

[BlueMar]

Hello gurus,

Need some help setting up a remote phone. I've set this up in the past and never have seen this issue. I've programmed the Public IP for the Call Server and HTTP Server. The phone seems to connect to the HTTP server and pulls all the config files. The phone then ask me to login with the extension and password. It seems to connect and register because I see the buttons about to be displayed but then it goes back to a screen that says "Registering". The phone is now stuck on that loop where I see the line appearance buttons and then back to Registering.

On the firewall the following ports are open and pointing to the IPO:
1718
1719
1720
49152-53247
5005

What can be going on here?

Figured it out!! I enabled H323 Transformation and that seems to have solved the issue.

thread940-1748894 close your port range down. See my comments this thread.
Consider vpn instead of NAT.

I'm clear but my fighter is down.
