             Summary: BRI locks up
                 Key: PRI-155
                 URL: https://issues.asterisk.org/jira/browse/PRI-155
             Project: LibPRI
          Issue Type: Bug
      Security Level: None
    Affects Versions: 1.4.13
         Environment: Asterisk 1.8.12.0, B410P
            Reporter: Lelio della Pietra
            Assignee: Richard Mudgett


Hello people,

 Asterisk 1.8.12.0, B410P, today downloaded libpri from SVN v2314 and dahdi from SVN 10741. Default configuration (unmodified dist files, with just spans and SIP users configured) with four ISDN point-to-point spans (the configuration is automatically generated by a script of mine and it work perfectly on any other remote device except this one).
 
 The endpoints are three Aethra Starvoice (one with two BRI and the other two with one BRI), supplied by British Telecom.
 
 After some use, randomly, an ISDN channel locks up (once a time, not all simultaneously) and stops responding; each placed call returns a "Everyone is busy/congested at this time". A "dahdi restart" command solves the problem but, after some minutes, it happens again.
 
 To get some debug data, I waited a channel lockup, enabled pri intense debug and placed a call through console, recording everything. The attached log (lines 249 and following) shows that there is a two-way traffic on the ISDN, but the call goes in congestion.
 
 I'm locked up. Any ideas?
