The invention relates to a method and system for routing calls from a telephone by private branch exchange in the telecommunications system. The private branch exchange usually has a server computer for recording and storing a caller line identifier (CLI). What happens is that the caller, that is to say the external telephone exchange operated by somebody, contacts the private branch exchange and instead of being met by a voice related prompt, the CLI of the caller has previously been stored and the routing preferences of that CLI have previously been stored and the call can be directly and automatically connected in accordance with the desired routing preference. A call arrives into the exchange in step (100) and once it is identified in step (102), that the CLI is already in the database, the personal preference for the caller is selected from the database in step (104). The call is routed automatically based on that preference in step (105). Various methods and systems for obtaining the routing preferences are described.
