This gateway used for call terminating. I have found following log on my
gateway. These are come from debug isdn q931.

part of entire log:

My question is

1. What kind of reason following errors occurred ?
2. How to solve that ?

  Cause i = 0x809E - Response to STATUS ENQUIRY or number unassigned
  Cause i = 0x82E6 - Recovery on timer expiry


Thanks for any help.

Best regards,
Tseveen.
