I have successfully setup several standalone Asterisk systems and they work great. I have the opportunity to integrate Asterisk with an existing Toshiba CHSUB672A PBX. I believe that the way I should connect the systems is through a T1 interface on the Toshiba, and a T100P on the Asterisk box like such: |-------------| |----------| | Toshiba PBX |(T1)---(T100P)| asterisk |(eth0)---(Wireless)---Phone |-------------| |----------| Does this seem correct? I am not familiar with proprietary PBX systems, and I need to determine if the Toshiba has a T1 interface. Their website describes the CTX670 as having one but does not have any information about the CHSUB672A. What is the best avenue for obtaining additional information about the PBX (such as it's features and configuration methods) since I don't have any documentation on it? Thanks a bunch, Barton
