    My RRAS doesn’t Answer ISDN

    My Windows 2000 Server has been configured to perform as a RAS Server.
    I installed a Multitech MT128SV ISDN adapter on it and configured the incoming connection properly. The problem is that when i tried to access the system from a remote site also using a Windows 2000 Server (and Professional too) Dial-up connection, the system stated that i do have an error 676 (busy line) and i never can connect.
    The funny part is that if i setup a Dialup connection in the same server that is to Receive the incoming calls, it will dial using one b channel, the ras will listen in the second and the connection wil be done.
    Anybody has some ideas to help-me go trough this?

      It sounds like the outbound side may be misconfigured. If you have not already done so, check that the remote site is set up for the correct ISDN modem, and that it can dial out.

      If you can, watch (or have someone watch) the outgoing modem and see if you ever get a B1 light.

      Check whether the remote site can successfully dial *anywhere* at all. The modem itself may be misconfigured, or have missing or bad SPID numbers. Your phone carrier will have an “ISDN help desk” which can check the line on the outgoing side back to the modem. Call them and ask for their help. If the ISDN modem at the remote site has bad SPIDs, it will not dial out.

      Some strange things related to ISDN:
      Some (not all) ISDN systems require that you dial 11 digits.
      Some different brands of ISDN modems will not talk to each other.
      ISDN modems do not usually talk to ISDN routers.

      Good luck.
