Blacklist - Not Working

I have trixbox 2.2.5 with FreePBX (Core) on PIII. It’s been working great for past 6 months or so.

I wanted to block few phone numbers, so naturally I looked into blacklist ( feature in FreePBX.

Well, to make a long story short, it just doesn’t work.

I have referred posts listed below and followed the advices, however, it still doesn’t do any good.

Please note,

  1. I have entered the phone numbers in two different formats, for example, 1222333444 and 2223334444.
  2. I am using a free DID from IPKall and I route sip calls to a specific extension in my server (and again, it’s been working great!)
  3. I have rebooted the server after making changes.
  4. According to FreePBX report (as well as one from trixbox), it catches correct caller id’s.
