What to do
4 Ensure the ISDN BRI line is working. Ask
your service provider to check this.
5 If the problem persists, contact your telecom
administrator or Nortel Networks distributor.
1 Does your telephone display "Offline Mode?"
If so, enter the Online SPRE code to go back
online.
2 Contact your telecom and data network
administrators. Perhaps network problems
caused the call to drop.
