I have a TAPI app that is accessing CME 4.1. I have CMETSP 184.108.40.206 installed on my PC. The problem is that sometimes when I call lineGetDevCaps() it returns a value of 0 in LINEDEVCAPS.dwNumAddresses. Normally it returns the number of assigned buttons on the phone.
I can sometimes clear the error by going through the TSP setup wizard and running the app again.
Has anyone seen this type of problem before?
