No access message.

Hello guys, If I run the latest version of openbsc and tried to register with my MS (Nokia 6310) to it, my phone finally says No Access. I see sending Channel Release several time in the debugging output. I also see increase/decrease usage several time. It has been a while not looking at the meaning of debug messages. I just use the standard config file for nanobts and changed a few parameters like unit_id, band, mcc and mnc, that's all. I noticed that I can't add an accept parameter, like before. Also in the config file I can't find anything like that, am I missing something? kind regards, nordin.
