Hello. I need help for a configuration in Elastix 2.0.2 In the office I put a card ISDN single port on a machine with Openvox B100P. IAX trunk with provider is OK (IN & OUT tested with client SIP) The ISDN card is connected to an harwdware Panasonic PBX with BRI port. The B100P is set in NT mode with the on-board impedance set to ON. The other side in TE mode. Obviously, the purpose is to pass calls from the trunk to the PBX hardware and vice-versa. When I try to make a call to the ISDN system response is "channel not available" The connection from B100P to PBX is made with an straight ISDN cable(but I tried with a cross also) and the control lights are both off. I also tried various configurations using FreePBX but without success and at this point I do not know more to get on. If someone could give me a hand I can post the configuration file, log or whatever. Thanks to anyone who could help me.
