When dial-in is configured on the Services Router, incoming ISDN calls are accepted by the Services Router. However, you can configure the Services Router to reject all incoming ISDN calls when dial-in is configured.
To configure the Services Router to reject incoming ISDN calls, include the reject-incoming statement at the [edit system processes isdn-signaling] hierarchy level:
- [edit system processes isdn-signaling]
- reject-incoming;
For more information about disabling dial-in, see the JUNOS System Basics Configuration Guide and the J-series Services Router Basic LAN and WAN Access Configuration Guide.
