[Freeswitch-users] conference not working

Hello, When an external user dials calls the main number they get asked to a conference number. They input it and get connected to a conference. When a local registered user dials the same conference number they get connected to a new conference. I need them both to be on the same conference. So if a user whether from internal or external dial a conference number they get transferred to the same conference. EX: External calls in and gets IVR. IVR says please enter conference number user inputs 3001 they go to 3001 Internal user dial from his phone 3001 he goes into conference 3001@X.XX.X where X is the IP address of the FS box. They don't see each other. Thanks,
