I am using LG P500 (Android 2.3 Gingerbread) and I need set 3CX for asterisk (realm = asterisk). I need set ID (only number or number@server), login, local pbx server...
I'm not clear on what the issue is. There are only a few parameters that are required, whether it be with a 3CX PBX, another make, or a VoIP provider, and it should be fairly obvious where they go. Which one is giving you the problem?
