we are using the "Dial Contact" action from within the GroupWise address
With GroupWise 7.x: The name and the phone number of the selected contact
have been transmitted completely to our TAPI application so it's possible to
make a call.
With GroupWise 8.0: Only the first characters of the name and the phone
number were transmitted.
e.g. "John Smith" results in "J" and "+49 123 456" results in "+" so our
application is not be able to make a call due to the incomplete phone

Is this a bug?

Thanks Juergen
