Using the ADCOI class, you may divide your users up in 4 categories to be allowed to use speed dialling numbers, also known as abbreviated dialling numbers.
Your users use either keysets or SLT phones (analog phones), and connected to an extension category (CAT) there is a parameter : TRAF. The TRAF consists of 8 digits. The 2 first digits (could be 00, 01, 02, 03) place the actual user in the category for abbreviated dialling ADCOI.
