Hi,<br /><br />&gt; 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.<br /><br />Because the IMSI is probably not an authorized one.<br /><br />&gt; 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.<br /><br />Yes, I&#39;ve seen multiple RF release too. I think there is a bug somewhere but didn&#39;t search yet.<br /><br />&gt; I just use the standard config file for nanobts and changed a few parameters like unit_id, band, mcc and mnc, that&#39;s all. I noticed that I can&#39;t add an accept parameter, like before. Also in the config file I can&#39;t find anything like that, am I missing something?<br /><br />The equivalent config parameter is &quot;auth policy&quot;. The defaut nano bts config file uses &quot;auth policy closed&quot; so all unauthorized phones will be rejected. You need t use &quot;auth policy accept-all&quot; if you want to authorized everyone without any check.<br /><br />    Sylvain
