We have a IPO500 v2 Rls. 8.1 with embedded vm. We programmed the AA with messages on *8101, *8201, *8301 and *8401. The problem is during the day the message *8101 plays and then the message *8401 plays after it. Is this a known problem? *8401 comes on on off hours and works fine but during the day both messages are heard. Any suggestions will be appreciated.
