I have a serious problem with an tapi-app for Panasonic TDA pbx. I have days or sometimes weeks without failures. We have days where it fails every hour also. The software is used as a server for dialing phone numbers. its written in c language. worked on windows xp pro Same problem occurs on all computers where I installed the software. Can anyone help me please?

Hi Micha_a, What is the OS that is running on the computer which has Panasonic TDA pbx application? Please consult Panasonic for further support and check whether this application is compatible with the current OS that is running.
