ISDN Layer 1 discarding incoming messages. Lack of buffers in pool.
The ISDN Layer 1 reading process is discarding incoming ISDN Layer 2 and 3 signalling messages because of a lack of buffers in the pool. Any new incoming calls and incoming clearing of existing calls will be ignored until this situation is resolved. Look out for the message saying "Layer 1 Discarding Messages Stopped", which means that the ISDN signalling channel is fully functional again although messages have been previously lost.
If this error occurs frequently it may indicate a problem with Blueworx Voice Response. Disable and re-enable the trunk on which the error occurred and try again. If the problem persists, stop and restart the signalling process using the Custom Server Manager menu option. All other trunks using the signalling process are disabled by taking this action. Restarting the custom server re-initializes the ISDN buffers in the system for use and should fix the immediate problem. If this does not solve the problem, shut down and restart Blueworx Voice Response. If none of the above is successful call Blueworx Support.
