I have a problem connecting a Grandstream ipphone to an asterisk. The ipphone is behind a nat router, I redirected UDP 5060 and 5004 to my phone. It connects well to the asterisk server. I can call outside and receive calls from outside without any problems. But if I call from this ipphone to another ipphone connected on the same asterisk server, using internal dialing, I can hear my correspondant, but he cannot. Do you have any idea? Thanks for advance.
