Im trying have added a Bri Trunk board(TN556D) and have set the interface field as 'network' and Country Protocol as '4' for Europe but I'm not sure if this is correct. Does anybody have the correct settings for this screen and also I'm needing to set up a trunk group for this BRI baord and i'm not sure what this settings are. I;ve set up UDP for various extensions to route via AAR to a trunk group but I haven't established what the correct settings are. This setup is to route calls to ISDN fax boards. Canm someone explain how I might do this?
