Samsung IDCS 28D system: How do I unblock access to outside lines? No lights show on the dead lines. Handset works in other offices.
Samsung IDCS 28D system: Any Handset plugged in to this office extension stopped connecting to all 4 phone lines. It still answers calls, has intercom, VM, & redials from the outgoing call log made before 10/11/22, when outside calling and phone lines became no-call to outside. It's like it was accidentally programmed to not allow calls to the outside. This has happened to 2 of our offices now! We appreciate any help!

Re:
It is possible that the outside lines have been blocked in the programming of the Samsung IDCS 28D system. You can try the following steps to unblock the outside lines:
On a phone that is working, press the TRANSFER button and dial 200.
Enter your system password. If you don't know your system password, you may need to contact your phone system administrator or service provider.
Press 713 for "Line Block Release".
Press the button for the line that is blocked (in your case, all 4 lines).
The display should show "RELEASE OK" for each line that is unblocked.
Hang up the phone.
If this doesn't work, it is possible that the phone system may need further troubleshooting or programming by a technician.
