I’ve now got the phone set up as, appropriately enough, “extension 61” on the local Asterisk PBX. This means, in practice, that it is now simply another handset here at the office. Except that “the office” stretches anywhere there is wifi. In other words, Johnny can pick up the phone in his office, dial “61” and my mobile will ring. Whether I am in the office next door or drinking absinthe with Olle in Copenhagen.
While this is technically elegant, it would also seem to signal a rather cataclysmic shift in the mobile marketplace: wifi is everywhere; once wifi-enabled phones are everywhere, is there any reason to have a SIM and be tied to expensive rates, dreadful service and poor features?
