More than 800 plus digital extensions was programmed incorrectly, instead of using itype 29 they used itype 21 for dbc 4223 digital phones. The phones are working okay under BC11 sp9 flatform but it will be upgraded very soon to TSW sp6. Is there way to mapped out the correct placement of keys for these digital extensions when the correct itype 29 is use when upgraded to the new released?Is there any ks converter software that changes the itype and key layout of digital phones for MD110/MX-one. Can anybody help me pls!
