How do I unblock a number on an AT&T BL102-2 cordless phone?
Answer
On the AT&T BL102-2 handset, open the menu with the arrow keys, go to Call Block, open Block List, highlight the number, and delete or unblock it. Then place a test call to confirm the number rings normally.
Follow these steps
Open Call Block
With the handset idle, use the arrow keys to find Call Block in the menu, then press SELECT.
You should see: The Call Block menu opens on the handset display.
Open the Block List
Go to Block List, then press SELECT to view saved blocked numbers.
You should see: You see one or more phone numbers on the Block List.
Find and remove the number
Use the up or down arrow to highlight the number you want to allow again. Choose the delete/unblock option shown on screen (wording may be Delete or Remove), then confirm if asked.
You should see: The number disappears from the Block List.
Test the number
Place a call to that number, and ask them to call you back once. Also check whether Quiet Hours or Anonymous call block is still enabled if problems continue.
You should see: Calls connect both ways, or you know another call-block setting is still active.

Extra tips
What to look for: Call Block or Block List in the handset menu, and the specific number still listed there.
Before you change anything: Confirm the phone model is AT&T BL102-2 (or the matching AT&T DECT handset). Have the blocked number handy so you can recognize it in the list. Do not factory-reset the base until you have tried Block List removal. Ignore unexpected callers asking for remote access to “fix call block.”
