It's almost absurd the lack of fanfare surrounding AT&Ts proposed phase out of the PSTN in favor of IP networks. We got number portability and wireless number portability, but the carriers still act as if they own our e.164 addresses and make the transfers arbitrarily difficult. We use phone numbers of SMS, but really we use individual address books, stored in devices, or synchronized with central repositories. We use names to identify people and have to work hard to ensure that our address books are not filled up with duplicates created because we used a one-off email address, or phone number and the phone wasn't able to merge it with an existing contact automatically. We have identity providers that can only represent a small portion of our identity, real names on Facebook and Google+, but cannot resolve that back to our phone numbers or find the best way to contact us at any given time. Presence, which was the real promise of IM and XMPP (and SIMPLE if you must) is not integrated. I cannot determine before hand whether somebody is available to talk on the phone, would prefer a text message, or if I should leave a push voice message they can listen to at their leisure. Even calling a company with a well designed IVR is still a confusing waste of time, when the device I am calling that system from is smart enough to contain any identifier or proof of identity that the called party would need, the protocols are artificially limited to phone numbers as identifiers. There is also no out of band solution to this problem, or the the problem of selecting what department I would prefer to speak with about a problem without navigating a menu that the interface on my device is not really designed to use. Think DTMF on an Android device where the screen shuts off.
