Is there some * code that will automatically add a caller (or last caller) to the X_BlockedCallers list?
Some how a particular number got added to this block list without actually manually entering it. I looked through the admin guide for such a code but couldn't find anything that matches this behavior.
Thoughts?
Found the issue.
Apparently *86 is defined as block last caller by default in the obi star codes. It's possible this code got dialed to check voice mail.
This post offers a solution on clearing the block listing using just a star code https://www.dslreports.com/forum/r30641411- .
What's interesting is the obi admin guide makes no mention of the block code but rather cancel repeat dial for *86 . Talk about a disconnect. This probably got changed in some firmware update but never documented. All the more reason why change logs are important!
A different obi, which was recently factory reset (following the 5757 firmware update) also shows block last caller for *86.
I changed *86 to *8686. Left the *99 in there too, just in case.
