I have a dual cabinet system with an ISDN card. System has been in place for 7 or 8 years. This pas week the system went haywire. Looks like most programming was lost and now have a couple of bad ports on the master cab. I reprogrammed system, which seems to have resolved issues except for one. on (9) extensions (all on cabinet-2), all outgoing calls are "Restricted". I have never had TRS/ARS activated in any way. Currently nothing is listed in an areas of restriction.
I can use a flex key or dial "9" to grab a line. As soon as I press any digit, the lcd displays "RESTRICTED"....
Please help.
