we recently upgraded from 7.0 to 9.0 and our TAPI will no longer work in 3rd party mode. it works fine in single party but as soon as we change it to 3rd party it stops functioning. our licenses show valid but it seems like it is not recognizing the CTI Pro license. I know TAPI is a nightmare and we try to stay away from it but has been functioning for years prior to the upgrade. If anyone has any ideas I would love to try them. Thanks!
