ISDN Layer 2 user initialization parameter error
A parameter was set incorrectly when initializing ISDN Layer 2 with parameters from the ISDN signalling section in the System Configuration menu option.
Select the System Configuration menu option, then select the ISDN signalling section and modify the failing parameter. Save your changes. If the trunk is still enabled, disable and re-enable it to pass the changed parameter to ISDN Layer 2.
