I'm testing this PBX from a few days and I'm finding some problems like: - Sometime during the clientregs can't register, reason=service unavailable. After some minutes (but 20!!!) it's registering correctly. This is happening 8/10 times a day. - Sometime even if the server is correctly registered to the provider I can't receive incoming calls - If I call my number with a cellular phone I can't receive the call and on the cellular I can't hear any tone sound. This is for now.....Anybody else with same problems? Any tip? I hope it will work everything better, I think it's a great PBX, simple to configure and with interesting functions.
