Can you use the cbti sounds with the cbus screen functions ? ie use the cbti sound library in the ctouch Can you add a cbti as a telephony device in toolkit - for me this 'option' is greyed out - if it appeared there instead of 'lighting' would it improve functionality? My cbti often doesn?t return all the numbers of a phone number ? virtually every time with a mobile number it returns 9 digits, missing mostly the first 0, but occasionally the last number
