We have several customers that have TN2501 Val Announce Boards, they do not use the Val Manager to manage the announcements, but they record the messages by dialing the feature access code and recording the message through the handset. The problem is that the recordings randomly disappear, some messages are never lost, and some can be accessed 3 or 4 times before they disappear. We have ended up removing the TN2501's and replacing them with TN750's. The TN2501 has the latest firmware, and this problem has occurred from R9 to MV1.1.
