With affect from Project Designer 1.22 we decided to remove the support for phonebook/call history and direct call in video conferencing systems.
We removde this function as very few installation over the last 3 years have been using this function.
This is done to ensure that we use our effort on maintaining and develop functions that you and your customer uses.
The function was only supported by as few devices:
Cisco C20, C60, C90, SX20
Polycom , RealPresence Group 500 and HDX7000-9000
LifeSize, Express 220
Of course it is still possible to control these devices but not all the devices are in Project Designer, so new devices will have to be made by you for the ones missing.
