576 / Problems for network or remote users Modular ICS 6.0 Installer GuideP0992638 03 Problems for network or remote users Remote feature code gets no response Possible problem A Norstar user has called into another Norstar system and is trying to activate a remote feature but gets no response after dialing the feature code. Solution 1. Make sure that the remote caller is dialing the feature code correctly. Use the asterisk (*) character, followed by the feature code, to activate a remote feature. Do not use ² for accessing features on a remote Norstar system. 2. Make sure that the remote user is dialing tones, not pulses, once the call is answered. Dialed number gets ringback and the wrong person Possible problem The digits sent by a switch at a central office or in the private network did not match any Received number, the Auto DN, or the DISA DN. The call has been routed to the prime telephone for the incoming trunk. Solution 1.

Connect a single-line DTMF telephone to a DID trunk input on the DID Trunk Cartridge. 2. Use the single-line telephone to enter a Received number that has been programmed for a target line in your system. Listen for ringback. 3. If you do not hear ringback, check that the target line is assigned to a telephone and that there is a prime telephone assigned for the DID trunk. 4.
