use this link to find explanations about isdn debugs:

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

in your case you have:

04:16:32.271 gmt: ISDN BR1/7 Q931: DISCONNECT pd = 8 callref = 0xBF

Cause i = 0x84A9 - Temporary failure

*84-the public network near the remote user (remote telco switch)

*A9: Temporary failure

An error occurs because of a network malfunction. Contact the telco if the problem persists
