I recently purchased a second-hand MIRAN II card. I want to use this to record an announcement telling the caller the line may be monitored for quality assurance before I send it to our customer service people. I have a DID built on the last TN but when I dial the ACOD it won't accept any user name I put in. I found some documentation saying USER (8737) will work but it doesn't for me. I can access the card using a terminal but not through the telephone. Any idea's?
