To unblock a number on a landline, the steps may vary depending on your phone service provider and the type of phone system you're using. Here are some general steps you can follow:
Unblocking a number on a landline depends on whether the block was set through your or directly on your physical handset . Method 1: Using Star Codes (Service Provider Level)
* Manage Block List ( 60): Dial *60 , follow the voice prompts to access your blocked list, and press * (star) followed by the number you wish to remove.
Some phones have a dedicated Block button. If you accidentally block a live call, pressing that same button again during the call may unblock it immediately.
* Deactivate Anonymous Call Rejection ( 87): To stop blocking calls from "Private" or "Unknown" numbers, dial *87 .
* Deactivate All Blocks ( 80): Dialing will often disable the entire call blocking feature on your line.
Modern cordless systems often store blocked numbers locally on the handset or base station.
