Understanding Unified Messaging Auto Attendants

In some companies (especially in East Asia), office telephones may not have letters on the keys of the telephone. This makes the spell-the-name feature that uses the DTMF interface almost impossible without a working knowledge of the key mappings. By default, Exchange 2007 Unified Messaging uses the E.161 key mapping. For example, 2=ABC, 3=DEF, 4=GHI, 5=JKL, 6=MNO, 7=PQRS, 8=TUV, 9=WXYZ. When inputting the combination of letters and numbers, for example “Mike1092″, the numeric digits are mapped to themselves. For an e-mail alias of “Mike1092″ to be entered correctly, the user will have to press the numbers 64531092. Also for characters other than A-Z and 0-9 there will not be a telephone key equivalent. Therefore, these characters should not be entered. For example, the e-mail alias “mike.wilson” would be entered as 6453945766. Even though there are 11 characters to be input, only 10 digits are entered by the user because the period (.) does not have a digit equivalent.
