I have set up two Asterisk servers to allow direct dialing to user extensions. How can configure the PBX to allow the remote Asterisk box to dial directly into the conference room? For example: PBX-A : In CA with extension 5XXX PBX-B : In NY with extension 6XXX I have a conference room set up in PBX-A with the number 5800. I would like PBX-B to dial 5800 and get place into the conference automatically. Currently when they call the #, they are getting the message "All circuits are busy now". I can transfer them into the room manually. Thanks!
