  Hello Srini, 

   

  I know that it won't be very helpful on your specific case, but here is the link where you can get the signification of the q.931 various disconnect cause codes :

   

  http://www.cisco.com/en/US/tech/tk801/tk379/technologies_tech_note09186a008012e95f.shtml

   

  In your case 0x80FF :

   

  Cause Code Origination Point => 80-the router

  Disconnect Cause Code =>  FF  - Interworking, unspecified - This cause indicates that an event occurs, but the network does not provide causes for the action. The precise problem is unknown.

   

  Kind regards.

  K. Rahmani
