Extension case are sensitive because when Asterisk attempts to match the extension dialed by a user to extension that is defined in context, the extension name should be precisely matched, including uppercase letters and small. Therefore, if a user calls extension "OFFICE" through their VoIP phone, Asterisk will not immediately run the commands we define for extension "Office". But in reality, extension names are not case sensitive in the sense that we cannot define different extensions based only on uppercase/ lowercase letters. It means we do not define the command for extension "Office" and "OFFICE" in a context.		i : Invalid
