Hi All, With some study from me, google and the help of the community I've managed to setup GnuGk based on the nat.ini file. The gatekeeper.ini file showed below have been tested on making calls (with a Cisco CTS-SX20 and a Sony PCS-G50) and receiving (number@IP) with the precious help of a community member. The problem is that now we've a client that doesn't accept IP calls, only ISDN and I can't make the Sony to dial successful, and when they try to call by number@IP it never reaches any of our VCs. They aren't very flexible and the troubleshooting is on our side. If I've understand it correctly they are using a Cisco Callmanager to do the calls. Maybe someone had already faced this issue or can see something wrong or missing from my configuration. Please advise. It was important for us to make this VC work (as always is for anybody) and if I can't make it work with GnuGk, I'll have to try to publish one of our VCs directly (and I still don't know what ports to forward on the firewall). We've asked the counterpart to dial 024456333@224.69.159.45 IPs are scrambled.
