All trunks lose registration


I have a new install of FREEPBX Asterisk (Ver. 11.16.0) - 64 bit, just downloaded yesterday, default install. All trunks register on boot, then after time out, they unregister.

I was replacing a working, but slightly crippled PBXIAF box and used the same trunk settings. I use Sipstation and also ViaTalk.

Can anyone give me some help here?
