Blacklisted caller

It appears that I may have optioned my phone number to be blacklisted. When I call in my call is directly sent to voice mail. if I call in from another phone number my call goes through to the extension.

How can I unblock a particular phone nubmer?

I noticed that my phone number is coming up in the log as filtered:

dialparties.agi: Filtered ARG3: 2000

any other extension works fine. The call is only blocked on this extension.

It appears that I had configured something wrong in the follow me section. After editing the follow me section, where I cleared the settings. Now calls go through.
